Opis:
The author introduces the problematics of the changing discourse of face. He argues that it requires a special attention given the scope and strength of mediatization processes permeating contemporary culture. In the article the consecutive historical phases of reflection on the cultural role of face are presented, spanning from ancient Greece and Middle Ages to late modernity. Such undertaking serves as a rich background for the detailed study of discourse of face in cinema and other screen based media.

Opis:
Development of facial recognition or expression recognition algorithms requires input data to thoroughly test the performance of algorithms in various conditions. Researchers are developing various methods to face challenges like illumination, pose and expression changes, as well as facial disguises. In this paper, we propose and establish a dataset of thermal facial images, which contains a set of neutral images in various poses as well as a set of facial images with different posed expressions collected with a thermal infrared camera. Since the properties of face in the thermal domain strongly depend on time, in order to show the impact of aging, collection of the dataset has been repeated and a corresponding set of data is provided. The paper describes the measurement methodology and database structure. We present baseline results of processing using state-of-the-art facial descriptors combined with distance metrics for thermal face re-identification. Three selected local descriptors, a histogram of oriented gradients, local binary patterns and local derivative patterns are used for elementary assessment of the database. The dataset offers a wide range of capabilities - from thermal face recognition to thermal expression recognition.

Opis:
Soft biometrics methods that involve gender, age and ethnicity are still developed. Face recognition methods often rely on gender recognition. The same applies to the methods reconstructing the faces or building 2D or 3D models of the faces. In the paper, we conduct study on different set of gender recognition methods and their mobile applications. We show the advantages and disadvantages of that methods and future challenges to the researches. In the previous papers, we examined a range variety of skin detection methods that help to spot the face in the images or video stream. On acquiring faces, we focus on gender recognition that will allow us to create pattern to build 2D and 3D automatic faces models from the images. That will result also in face recognition and authentication, also.

Opis:
Biometric databases are important components that help improve the performanceof state-of-the-art recognition applications. The availability of more andmore challenging data is attracting the attention of researchers, who are systematicallydeveloping novel recognition algorithms and increasing the accuracyof identification. Surprisingly, most of the popular face datasets (like LFW orIJBA) are not fully unconstrained. The majority of the available images werenot acquired on-the-move, which reduces the amount of blurring that is causedby motion or incorrect focusing. Therefore, the COMPACT database for studyingless-cooperative face recognition is introduced in this paper. The datasetconsists of high-resolution images of 108 subjects acquired in a fully automatedmanner as people go through the recognition gate. This ensures that the collecteddata contains real-world degradation factors: different distances, expressions,occlusions, pose variations, and motion blur. Additionally, the authorsconducted a series of experiments that verified the face-recognition performanceon the collected data.

Opis:
This paper explores the notion of compassion and points to some intricacies inherent in it, in particular the paradox of egocentrism. Most ambiguous is its ontological status: is it an emotion, a virtue, a moral commitment, or a neurological reflex? Each category entails different implications for the process of educating compassionate beings. The conclusion is that genuine compassion is, from the very beginning, not just mere feeling, it is based on the recognition of rights of others. A person in need is much more than the object of our noble compassionate feelings and caring help, she is the subject of rights.

This qualitative exploration is a follow-up study to the quantitative research published in a peer-reviewed international journal in 2023. Generally, the study delved into the transition experiences and preferences of 20 Filipino education supervisors in relation to their supervisory practices in over 80 Philippine public schools. Through validated open-ended interview questions, the responses were gathered and subsequently subjected to thematic analysis, which resulted in the emergence of the following themes: (1) the adjustments and challenges of the supervisors as they switched back from technology-assisted to in-person supervision; and (2) their preferred mode of supervision in the new normal of education.

‘Bloom's Taxonomy of Educational’ Objectives has been a mainstay of educational theory for over fifty years. In 2001 the original taxonomy was revised. This article uses Bloom's revised framework to design small groups in online classes. The author draws on his extensive experience in using small groups in face-to-face classes as well as fifteen years of experience with small groups in a variety of undergraduate and graduate online classes. He particularly addresses the need to design small groups that focus on Bloom's higher order category of „Create”. Suggestions for future research are also included.

Opis:
The structure of conversation is a subject of many empirical researches along the Conversational Analytical point of view. Scholars have agreed that nonverbal signals which are called regulators act as a kind of traffic signals that aid in the flow of interactions. This paper studies the use of nonverbal regulators in Hausa social interactions, through the use of data consisting of natural face-to-face interactions taken from multiple settings. The research discovers that Hausa peoples’ interaction, especially in face-to-face settings, is marred with different gestures and postures acting as conversational regulators. Beyond regulating the interaction, these gestures and postures contribute to meaning making and influence communication outcomes.

Opis:
This study compared the challenges of 20 education supervisors in executing technology-assisted and in-person supervision. These supervisors oversee the curriculum articulation for over 200,000 Filipino learners in 85 Philippine public schools. Results showed that technology-assisted supervision (Mn=3.18; Md=3.26) outscored in-person supervision (Mn=2.88; Md=2.95), with the former mode of supervision obtaining higher perceived challenges than the latter. However, the Wilcoxon Signed Ranks Test found an insignificant difference in their degrees of challenges when grouped according to the mode of supervision used (p-value=.191>.05), indicating the need to further explore the supervisors’ experiences to improve their supervision quality.

Opis:
There are many ways to describe and recognize the human face. The paper shows one of them - the feature based method. It also considers usefulness of the face geometrical measurements in recognition and also the geometrical dependence on the features. The paper treats on the feature points detection and takes into consideration six of them, which are: two eyes, two eyebrows, nose and lips. It shows a detailed algorithm of the proposed method and describes its advantages and disadvantages. It also describes a filtering, feature points extraction and gives formulas for calculation of a face likeness coordinates. At the very end it concludes with experiments and examples of the proposed method.

Opis:
Facial emotion recognition (FER) is an important topic in the fields of computer vision and artificial intelligence owing to its significant academic and commercial potential. Nowadays, emotional factors are important as classic functional aspects of customer purchasing behavior. Purchasing choices and decisions making are the result of a careful analysis of the product advantages and disadvantages and of affective and emotional aspects. This paper presents a novel method for human emotion classification and recognition. We generate seven referential faces suitable for each kind of facial emotion based on perfect face ratios and some classical averages. The basic idea is to extract perfect face ratios for emotional face and for each referential face as features and calculate the distance between them by using fuzzy hamming distance. To extract perfect face ratios, we use the point landmarks in the face then sixteen features will be extract. An experimental evaluation demonstrates the satisfactory performance of our approach on WSEFEP dataset. It can be applied with any existing facial emotion dataset. The proposed algorithm will be a competitor of the other proposed relative approaches. The recognition rate reaches more than 90%.

Opis:
The author analyses two specific communicative events within the political discourse in the current work. The analysis involves a dialogue between two politicians who meet face to face in a TV studio and the subsequent communication taking place on the Internet after the dialogue was made public. The utilization of offensive communicative strategies is a typical feature in political media communication where a communicating party attacks the communication counterpart with the intention of challenging his/her positive face and emphasizing his/her negative character traits in front of potential voters, while at the same time emphasizing his/her own positive values. For this reason, the author analyses the individual strategies employed by politicians with this intention in a particular communicative event. The work provides an entire chapter dealing with strategies used by participants in an Internet discussion. In this case, the communication takes place among speakers who do not know each other, so the aim of the work is to investigate whether attacks against one’s face take place even in this kind of communication, and if so, what personality traits of the communicants are attacked.
