Artykuł przedstawia metodę klasyfikacji i zliczania pojazdów na podstawie danych wideo. Wejściowa sekwencja obrazów składa się z ramek pobranych ze strumienia wideo otrzymywanego z kamery umieszczonej nad drogą. Poszczególne obrazy wejściowej sekwencji obrazów są przetwarzane oddzielnie. Definiowane są dwa pola detekcji, początkowe pole detekcji i końcowe pole detekcji. Obrazy wejściowej sekwencji obrazów są konwertowane do reprezentacji punktowej. Obliczana jest suma punktów krawędziowych dla każdego pola detekcji. Na podstawie sum punktów krawędziowych wyznaczane są stany pól detekcji. Analiza stanów pól detekcji umożliwia klasyfikację i zliczanie pojazdów. W artykule zamieszczono wyniki pomiarów.
The paper presents a method of vehicle classification and counting on the basis of video data. The input image sequence consists of consecutive frames taken from the video stream obtained from the camera placed above a road. Individual images from the input image sequence are processed separately. Two detection fields are defined, the initial detection field and the final detection field. Images from the input image sequence are converted into point representation. The sum of the edge points is calculated for each detection field. On the basis of the sums of edge points, states of the detection fields are determined. Analysis of the states of the detection fields allows vehicle classification and counting. Experimental results are provided.

Opis:
The use of audiovisual recording devices is changing the practice of qualitative research. Extensive corpus of data can be generated in (shortterm) focussed fieldwork. Nevertheless, methods to analyse video data are still in an experimental stage. This article explores the benefits and limitations of applying sociolinguistic genre analysis to audio-visual data. This is illustrated with a case study, based on the videotaped »deep-trance vision« of a New Religious Movement’s spiritual leader, which is one the most famous contemporary religious visionaries in Germany. The analysis aims to reconstruct the construction of this religious experience of transcendence from the perspective of its followers. We will examine three different levels of communication (a) the inner context, exploring the textual, gestural, mimical and prosodic aspects, (b) the intermediate level where the focus lies on the setting and decorum, and finally (c) the outer context, focussing on the social embedding of this form of »transcendent« communication and its filmic presentation. The article closes with a reflection on the need to combine hermeneutic analysis of case studies based on textual analysis with ethnographic field data and observation to contextualise its interpretation.

Opis:
Video surveillance on both marine and inland waters still only plays a mainly auxiliary role in vessel traffic observation and management. The newest technical achievements in visual systems allow camera images to be used in more sophisticated tasks, such as automatic vessel recognition and identification in observed areas. With the use of deep learning algorithms and other artificial intelligence methods, such as rough sets and fuzzy sets, new functions can be designed and implemented in monitoring systems. In this paper the challenges that were encountered and the technology that has been developed in managing video streams are presented as well as the images needed for tests and proper operation of the designed Ship Recognition and Identification System (SHREC). The current technologies, typical setups and capabilities of cameras, with regard to existing on-water video monitoring systems, are also presented. The aspects of collecting the test data in the Szczecin Water Junction area are also described. The main part of the article focuses on presenting the video data pre-processing, storing and managing procedures that have been developed for the purposes of the SHREC system.

The paper presents the analysis and discussion of video detection data usage for discrete transport systems safety improvement. The Autonomous Vehicles (AV) and the Augmented Reality (AR) research in connection with a Driving Assistance (DA) are presented. This article is going to show where the border between those two fields of interest is and how they are going to influence on the future of automotive. The proposal of the AR system – based on soft-computing methods used for an object classification problem – is given. The input data are taken from the real traffic monitoring system located at the set of roads in Poland. Data from the monitoring devices are used to analyze the travel time of vehicles – elements of the transportation system. The travel time model taking into account the real road situation is built. The proposed solution can be an essential tool for the owner and administrator of the transportation systems

Opis:
The author argues that visual methods are at the crossroads. They can remain in a niche or move into the mainstream by also addressing all people using visual materials. In the social sciences, visual methods encompass photography, video, and graphic representations. With respect to the visual, one has to note that all interpretations that are ontologically dependent on photography require more interpretation. 'Looking at' means 'being framed by,' and this means also the picture maker who is also considered to be a viewer. For the social sciences, pictures provide us with personal insights as well as with a personal record of spatial and social relationships. On this basis one may raise questions like 'how pattern variations occur over time?', 'how are social processes organized?', or 'what is the role of emotion in social life?' These are issues, the author continues, to which visual data can contribute. It may be added that methodological discussion should, however, besides the areas of visual data generation, analysis and interpretation also include solutions for the problem of communicating research findings. Some of these questions can be approached via controlled photo-observation, photo-elicitation techniques and imagery provided by the subjects themselves. Finally, the author turns to the question of what remains to be done? Here, he delineates three main areas: (1) evaluating the theoretical and conceptual basis of visual research, (2) creating public databases for the development and testing of theories, (3) defining 'best practices' for visual research.

Opis:
Modern Intelligent Transport Systems incorporate the traffic control strategies that are based not only on long term traffic analysis and forecasts, but also on the real time events detection like accidents or high congestion. The flexibility of these systems depends on accurate and precise data set describing the current state of road network. To estimate it, the data from various sources like: video surveillance, induction loops or vehicles itself (Vehicle to Infrastructure communication -V2I) is gathered. Excluding detection errors, the video surveillance data is a reliable source of general information about the traffic flow. On the other hand, the vehicle communication can provide less reliable, but more detailed information about a particular vehicle like: its engine state or planned manoeuvre. Unreliable or forged C2I information can be used to disturb traffic or to gain a higher priority on the road. The paper reviews the fusion algorithms that are used to merge data from video tracking algorithms and vehicular networks. Based on the survey, a weighted fusion algorithm is proposed that estimates the acquired data reliability. The algorithm uses the video surveillance data as a filter for C2I communication. Finally, applications for microscopic traffic models and safety issues are taken into consideration.

Opis:
The article describes the process of creating 3D models of architectural objects on the basis of video images, which had been acquired by a Sony NEX-VG10E fixed focal length video camera. It was assumed, that based on video and Terrestrial Laser Scanning data it is possible to develop 3D models of architectural objects. The acquisition of video data was preceded by the calibration of video camera. The process of creating 3D models from video data involves the following steps: video frames selection for the orientation process, orientation of video frames using points with known coordinates from Terrestrial Laser Scanning (TLS), generating a TIN model using automatic matching methods. The above objects have been measured with an impulse laser scanner, Leica ScanStation 2. Created 3D models of architectural objects were compared with 3D models of the same objects for which the self-calibration bundle adjustment process was performed. In this order a PhotoModeler Software was used. In order to assess the accuracy of the developed 3D models of architectural objects, points with known coordinates from Terrestrial Laser Scanning were used. To assess the accuracy a shortest distance method was used. Analysis of the accuracy showed that 3D models generated from video images differ by about 0.06 ÷ 0.13 m compared to TLS data.
Artykuł zawiera opis procesu opracowania modeli 3D obiektów architektonicznych na podstawie obrazów wideo pozyskanych kamerą wideo Sony NEX-VG10E ze stałoogniskowym obiektywem. Przyjęto założenie, że na podstawie danych wideo i danych z naziemnego skaningu laserowego (NSL) możliwe jest opracowanie modeli 3D obiektów architektonicznych. Pozyskanie danych wideo zostało poprzedzone kalibracją kamery wideo. Model matematyczny kamery był oparty na rzucie perspektywicznym. Proces opracowania modeli 3D na podstawie danych wideo składał się z następujących etapów: wybór klatek wideo do procesu orientacji, orientacja klatek wideo na podstawie współrzędnych odczytanych z chmury punktów NSL, wygenerowanie modelu 3D w strukturze TIN z wykorzystaniem metod automatycznej korelacji obrazów. Opracowane modele 3D zostały porównane z modelami 3D tych samych obiektów, dla których została przeprowadzona samokalibracja metodą wiązek. W celu oceny dokładności opracowanych modeli 3D obiektów architektonicznych wykorzystano punkty naziemnego skaningu laserowego. Do oceny dokładności wykorzystano metodę najkrótszej odległości. Analiza dokładności wykazała, że dokładność modeli 3D generowanych na podstawie danych wideo wynosi około 0.06 ÷ 0.13m względem danych NSL.

Opis:
COVID-19 has been a turning point for online learning across the world, but the remarkable story has been the meteoric growth of synchronous or “live” online education. As instructors around the world have turned to video conferencing platforms to teach, a lot of instructor feedback has recently emerged on a variety of topics. One of the key emerging issues for instructors and institutions has been extracting and consolidating data on student engagement and learning outcomes. This paper attempts to identify and classify the types of learning data required to understand student learning behavior in synchronous (or “live”) online classes based on a multitude of factors such as immediacy, consolidation, and availability to different stakeholders at different points in time. Further, an attempt is made to assess how popular video conferencing platforms address the issues of data generation, presentation, and collation. Lastly, the paper also proposes an alternative approach that can potentially help create data in an easier, more efficient manner.

Opis:
Article focuses on the problem of copyright protection of spatial data used to create and perform multimedia works. Multimedia are hybrid works because they are constructed from two main layers (audiovisual work and computer program) but should be treated as one product according to the copyright. Thus spatial data included inside such a works have to be protected within them as a one product. Video games were chosen as an example of multimedia (hybrid) works. First chapter shows crucial role of (mostly) artificial spatial data in the creation and usage of video games. Spatial data describe game environment’s location of every (audio)visual object but are encoded in, and used by computer program to perform video game properly. As such spatial data are one of the reason for treating video game as unified product, consisting amalgamation of its elements. Because spatial data are binder of the video game both layers, they should not be subject of separated copyright protection. Thus to protect spatial data included in video game, the video game itself needs to be protected properly. However, because video games are hybrid works, they legal nature is not determined yet. There is also no legal definition or specific copyright regulation for video games. Because of this legal loophole, different doctrinal concepts together with European Court of Justice judgements, on the video game’s copyright protection, were analyzed. This was analyzed in chapter two. Conclusions consist statement that lack of video games legal nature’s determination, and caused by this lack of specific copyright protection of video games may lead to not enough copyright protection of the video game as a whole product as well as spatial data included inside. Specific regulation instead of casuistic judgements is needed, for ensure the video games market grows.

Opis:
W artykule zaproponowano metodę uzupełnienia danych z Naziemnego Skaningu Laserowego (NSL) w postaci chmury punktów o zbiór punktów wygenerowanych z obrazów wideo, w przypadku gdy z pewnych przyczyn dany obiekt nie został w pełni zeskanowany. Niniejszy artykuł zawiera pełny opis procesu opracowania modelu 3D obiektu na podstawie obrazów wideo wraz z wyprowadzeniem algorytmu umożliwiającego obliczenie n-tej klatki wideo wykorzystanej do opracowania Numerycznego Modelu Obiektu. Proponowaną metodę wyróżnia zastosowanie w komercyjnej kamerze video obiektywu o stałej ogniskowej. Analizę dokładności chmury punktów wygenerowanych z obrazów wideo wykonano w oparciu o dane referencyjne w postaci punktów z Naziemnego Skaningu Laserowego. W tym celu odjęto od siebie modele 3D wygenerowane na podstawie danych video i NSL. Przeprowadzone badania wykazały, że dla powierzchni płaskich błąd średni danych wideo względem danych NSL wynosi około 4 cm (dla badanych obiektów: 3,7 cm i 4,4 cm), natomiast dla obiektu o zróżnicowanym kształcie wynosi 5,7 cm.
In a paper, a method of complement Terrestrial Laser Scanning (TLS) data with a set of points from video data is proposed. The method can be useful when an object has not been fully scanned. The paper contains a complete description of a process of creating 3D models of objects on the basis of video images. In the paper, a new algorithm of automatic video frames selection for the model 3D creating is proposed. As distinct from other techniques, the proposed method uses a video camera with the fixed focal length. In order to assess the accuracy of the developed 3D models of measured objects, points with known coordinates from Terrestrial Laser Scanning were used. The accuracy analysis relied on subtracting of the 3D surface models in a GRID form which had been extracted from TLS and video data. The accuracy analysis showed that the accuracy of 3D models generated from video images is about 4 cm for flat surfaces (for measured objects: 3.7 cm and 4.4 cm), and 5.7 cm for an object with complicated shape.

Opis:
Advanced terrain models are currently commonly used in many video/computers games. Professional GIS technologies, existing spatial datasets and cartographic methodology are more widely used in their development. This allows for achieving a realistic model of the world. On the other hand, the so-called game engines have very high capability of spatial data visualization. Preparing terrain models for the purpose of video games requires knowledge and experience of GIS specialists and cartographers, although it is also accessible for non-professionals. The authors point out commonness and variety of use of terrain models in video games and the existence of a series of ready, advanced tools and procedures of terrain model creating. Finally the authors describe the experiment of performing the process of data modeling for “Condor Soar Simulator”.

In this paper, a detailed analysis of the content of the bitstream, produced by the HEVC video encoder is presented. With the use of the HM 10.0 reference software the following statistics were investigated: 1) the amount of data in the encoded stream related to individual frame types, 2) the relationship between the value of the QP and the size of the bitstream at the output of the encoder, 3) contribution of individual types of data to I and B frames. The above mentioned aspects have been thoroughly explored for a wide range of target bitrates. The obtained results became the basis for highlighting guidelines that allow for efficient bitrate control in the HEVC encoder.

In this study the first part of the experimental data was recorded in a data acquisition station, and another one was recorded with a high speed camera. The data recorded using the acquisition station was recorded with higher frequency than the time between two subsequent frames of the film. During the analysis of the experimental data the problem was related to the synchronization of measurement from acquisition station and data recorded with a camera. In this paper the method of synchronization of experimental data has been shown. A laser- phototransistor system has been used. The data synchronization was required in scaling of sampling frequency in the investigated time series.
