Opis:
In this paper a survey of analog application specific integrated circuits (ASICs) for low-level image processing, called vision chips, is presented. Due to the specific requirements, the vision chips are designed using different architectures best suited to their functions. The main types of the vision chip architectures and their properties are presented and characterized on selected examples of prototype integrated circuits (ICs) fabricated in complementary metal oxide semiconductor (CMOS) technologies. While discussing the vision chip realizations the importance of low-cost, low-power solutions is highlighted, which are increasingly being used in intelligent consumer equipment. Thanks to the great development of the automated design environments and fabrication methods, new, so far unknown applications of the vision chips become possible, as for example disposable endoscopy capsules for photographing the human gastrointestinal tract for the purposes of medical diagnosis.

Opis:
An analogue median filter, realised in a 0.35 μm CMOS technology, is presented in this paper. The key advantages of the filter are: high speed of image processing (50 frames per second), low-power operation (below 1.25 mW under 3.3 V supply) and relatively high accuracy of signal processing. The presented filter is a part of an integrated circuit for image processing (a vision chip), containing: a photo-sensor matrix, a set of analogue pre-processors, and interface circuits. The analysis of the main parameters of the considered median filter is presented. The discussion of important limitations in the operation of the filter due to the restrictions imposed by CMOS technology is also presented.

Opis:
The article outlines the video registration method as well as research based on obtained video footage of the characteristics of traffic flow. The method is flexible and makes it possible to research various traffic characteristics. The article presents the method’s assumptions and the manner in which traffic flow characteristics were measured. The method of registering traffic flow parameters on video was implemented in 2012 in selected sections of Katowice’s road network. An important feature is the possibility of traffic flow parameterization with the use of popular camcorders. The thus-obtained footage is processed using so-called open library vision graphics procedures in order to establish traffic flow characteristics in near real-time.

Opis:
Demand of high speed production not only increases the complexity of today's CNC process, but also increases the risks and possibility of collision because of the difference between real (machining) and virtual scenes (CAD/CAM process). Idea here is to make this process more intelligent by processing image taken from the real or virtual machine scenes. Identify objects (already known in the CAD database), obtain safe and efficient trajectories that will modify the previous known trajectories from the CAM systems and will be used finally in real machining environments. This work more focuses to improve trajectory generation, collision avoidance and communication in CAD/CAM systems by image processing technique. Safe and Efficient Trajectory (SET) algorithm for point trajectory is discussed along with its extended version for object trajectory known as Rectangular Enveloped object Safe and Efficient Trajectory (RESET) algorithm that will perfectly generate safe un-functional trajectories [3] for multi-axis machine tool envelop. Meanwhile scene objects are detected and identified by image processing tool while trajectory and setup is optimized and improved accordingly in order to avoid collision. This generated trajectory can be used for setup correction before and after production or for "real times/online" production. Finally work has been validated through real and virtual machine scene images.

Multisensory systems are often used in security systems for border surveillance and protection as well as in various military systems like fire control systems. In security systems combined infrared and vision cameras are used to increase effectiveness and detection efficiency. The reason for wide use of infrared cameras in many surveillance and industrial areas is registration of an image in the infrared waveband, which provides new information about the observed process. A traditional vision camera works in the visible spectrum and is applied in security systems for face recognition and identification providing evidence to incidents in the monitored area. A system consisting of infrared and visible cameras allows observing the scene in two wavebands merging advantages of both technologies. The image digital processing system must be designed with consideration about differences between infrared and vision images. Images from different cameras, besides different information in the picture, can also have different resolution, frame rate and data width. The paper presents an approach to integrating a video channel with infrared channel despite of different pixel clock frequencies and different resolutions of the cameras. A method for integration of two different image data streams from visual and infrared cameras in a single digital system is presented. Furthermore, a method for providing display functionality on monitors working in two different video standards is proposed. The presented system has been tested and

In this article, the authors focused on the widely used aluminium extrusion technology, where the die quality and durability are the essential factors. In this study, detailed solutions in the three-key area have been presented. First is applying marking technology, where a laser technique was proposed as a consistent light source of high power in a selected, narrow spectral range. In the second, an automated and reliable identification method of alphanumeric characters was investigated using an advanced machine vision system and digital image processing adopted to the industrial conditions. Third, a proposed concept of online tool management was introduced as an efficient process for properly planning the production process, cost estimation and risk assessment. In this research, the authors pay attention to the designed vision system’s speed, reliability, and mobility. This leads to the practical, industrial application of the proposed solutions, where the influence of external factors is not negligible.

Opis:
The paper presents a vision based approach and neural network techniques in surface defects inspection and categorization. Depending on part design and processing techniques, castings may develop surface discontinuities such as cracks and pores that greatly influence the material’s properties Since the human visual inspection for the surface is slow and expensive, a computer vision system is an alternative solution for the online inspection. The authors present the developed vision system uses an advanced image processing algorithm based on modified Laplacian of Gaussian edge detection method and advanced lighting system. The defect inspection algorithm consists of several parameters that allow the user to specify the sensitivity level at which he can accept the defects in the casting. In addition to the developed image processing algorithm and vision system apparatus, an advanced learning process has been developed, based on neural network techniques. Finally, as an example three groups of defects were investigated demonstrates automatic selection and categorization of the measured defects, such as blowholes, shrinkage porosity and shrinkage cavity.

W pracy przedstawiono możliwości zaawansowanego przetwarzania, pomiaru oraz analizy cyfrowych obrazów wizyjnych i termalnych w środowisku nowej wersji autorskiego systemu "Vision Plus". Opracowana zewnętrzna biblioteka "Vision" umożliwia integracje obsługi, unifikacje narzędzi do przetwarzania oraz fuzje różnych danych cyfrowych na platformie pakietu "Vision Plus". Bibliotekę "Vision" charakteryzują m.in. następujące cechy: implementacja różnych rodzajów formatów danych, obsługa dowolnych rodzajów piksela, kontenery pozwalające na przechowywanie danych obrazowych, kalibracja metrologiczna obrazu, rozbudowa funkcji importu i eksportu danych, rozbudowana komunikacja z innymi programami, nakładanie obiektów graficznych wyznaczonych metodami fotogrametrycznymi, grupowanie obrazów, narzędzi oraz danych wejściowych, optymalizacja interfejsu u_ytkownika. Dodatkowy moduł "Thermal Analyst", wykorzystujący podejście obiektowe, jest funkcjonalnie zintegrowany z biblioteka "Vision". Przeznaczony jest do zaawansowanych operacji oraz analiz na cyfrowych obrazach termalnych i wizyjnych oraz ekstrakcji informacji. Program "Thermal Analyst" obsługuje maski oraz opracowane wtyczki (plugin): Subtractor, NUC (Non Uniformity Correction dla matryc detektorów termowizyjnych), Fourier Transform, Statistic (statystyka dla wybranych obrazów), Export to AVI (tworzenie sekwencji video), 2D Projective Transformation, Combine Images (działania arytmetyczne na obrazach). Biblioteke "Vision" i program "Thermal Analyst" wykonano głównie w języku Object Pascal przy wykorzystaniu pakietu Borland Developer Studio 2005. W pracy zostały omówione dwa przykłady typowych aplikacji bliskiego zasięgu (diagnostyka medyczna, badanie deformacji żelbetonowej belki stropowej). Opracowanie w środowisku multisensoralnego systemu "Vision Plus" obrazów cyfrowych pozyskanych sensorami wizyjnym i termalnym wykonano stosując specjalizowane procedury przetwarzania, pomiaru i łączenia danych (data fusion).
The paper presents the possibilities of advanced processing, measuring and analyzing visual and thermal digital images in the newest version of the "Vision Plus" authors’ system environment. The "Vision" external library enables service integration, unification of digital processing tools and various digital data fusion on the "Vision Plus" package platform. The "Vision" library is characterised by the following features: various data formats implementation, service of various pixel types, converters enabling image data storage, metrological image calibration, extension of data import and export functions, expanded communication with other applications, overlapping of graphic objects determined by photogrammetric methods, images, tools and input data grouping and user interface optimisation. The new, additional "Thermal Analyst" module created in an object-approach is functionally integrated with the "Vision" library, and is used for advanced processing and analysis of thermal and visual digital images, as well as for information extraction. It additionally operates on masks and on created plugins: Subtractor, NUC (Non Uniformity Correction for thermovision detector matrixes), Fourier Transform, Statistic (statistics of chosen images), Export to AVI (converting into a video sequence), 2D Projective Transformation, Combine Images (arithmetical operations on images). The "Vision" library and "Thermal Analyst" software were created mainly in the Object Pascal programming language using Borland Developer Studio 2005 package. Moreover, the paper describes two typical examples of close range applications: medical diagnostics and measurement of a reinforced concrete tie-beam deformation. In the multisensoral "Vision Plus" system, dedicated processing, measuring and digital data fusion procedures are applied in the process of elaboration of digital and thermal images, which were obtained by video and thermal sensors.

Abstract: In visual information processing, two kinds of vision are distinguished: vision-for-perception related to the conscious identifi cation of objects, and vision-for-action that deals with visual control of movements. Neuroscience suggests that these two functions are performed by two separate brain neural systems – the ventral and dorsal pathways (Milner and Goodale, 1995). Two experiments using behavioural measures were conducted with the objective of exploring any potential interaction between these two functions of vision. The aim was to combine in one task methods allowing for the simultaneous capture of both perceptual global processing and affordance extraction and to check whether they infi uence each other. This aim was achieved by employing the paradigms of Navon (1977) and Tucker and Ellis (1998). A compound fi gure was created made up of objects with handles that might or might not have orientation congruent between levels. The results revealed that while the affordance effect occurred every time, the Navon effect appeared only when subjects focused their attention on object elements responsible for inconsistence within compound fi gure. Most importantly, even when these two effects occurred at once, they had no effect on each other. Results from the study failed to confi rm the hypothesis about interaction and gives support to the view that vision-for-perception and vision-for-action tend to act as separate systems.

Opis:
A new camera based machine vision system for the automatic inspection of surface defects in aluminum die casting was developed by the authors. The problem of surface defects in aluminum die casting is widespread throughout the foundry industry and their detection is o f paramount importance in maintaining product quality. The casting surfaces are the most highly loaded regions of materials and components. Mechanical and thermal loads as well as corrosion or irradiation attacks are directed primarily at the surface of the castings. Depending on part design and processing techniques, castings may develop surface discontinuities such as cracks or tears, inclusions due to chemical reactions or foreign material in the molten metal, and pores that greatly influence the material ability to withs tand these loads. Surface defects may act as a stress concentrator initiating a fracture point. If a pressure is applied in this area, the casting can fracture. The human visual system is well adapted to perform in areas of variety and change; the visual inspection processes, on the other hand, require observing the same type of image repeatedly to detect anomalies. Slow, expensive, erratic inspection usually is the result. Computer based visual inspection provides a viable alternative to human inspectors. Developed by authors machine vision system uses an image processing algorithm based on modified Laplacian of Gaussian edge detection method to detect defects with different sizes and shapes. The defect inspection algorithm consists of three parameters. One is a parameter of defects sensitivity, the second parameter is a thres hold level and the third parameter is to identify the detected defects size and shape. The machine vision system has been successfully tested for the different types of defects on the surface of castings.
