There exist many methods for facial recognition, such as eigenface, templates, artificial neural networks, etc., based on the given facial sample data (patterns). When an input facial image (target) involve simple geometrical transformations and illumination, the performance of these methods are not very satisfactory. In this thesis, following Li et al., we propose a new face recognition system, which can eliminate translation, rotation, scaling, and prospective transformations of facial images automatically, and can also eliminate illumination. According to facial features, we use this method to find the best transformation and the closet illumination, and then to eliminate them for identification by the best matching between a target and the patterns. Finally, we use the least squares method to recognize the target. This method is validated by numerical examples.

This qualitative study employing ethnomethodology investigated whether previously employed African women between 50-59 years, termed near-old, turned to learning as a coping strategy after losing their jobs. Reflexive discussions, termed ‘herstories,’ were analysed. Whether the women experienced true crisis as a result of cessation from work, how they made meaning as they aged and to what extent retirement was a catalyst for learning formed the central lines of probing. The findings revealed that the near-old women did not consider the transition to old age a crisis. Crises in their experiences were more permanent and emotionally devastating. Meaning schemes and perspectives were transformed as they encountered unbearable work situations. Critical reflection on the situation led to action resulting in them exiting formal employment. There was strong evidence of self-directed and life-long learning. The women sought out new knowledge and skills in order to cope in the competitive work of consultancy. Instances of positive adult development attested to Mezirow’s theory of transformative learning and Brookfield’s reflective thinking. The study highlighted the need to use adult education strategies in order to promote critical reflection and to ‘conscientise’ older people about their deeply embedded beliefs that are often entrenched by their socialisation.

This research explored the complexity of language teacher identity from a holistic perspective involving two features: the integration of teachers’ personal and professional experiences, and the application of conscious/rational and intuitive/tacit thought processes. The study examined four ESL teachers’ beliefs, perceptions, and interpretations about the influences of their important personal, educational, and professional experiences on the development of their teacher identity. It also investigated the overall impact of an autobiographical reflective process combined with a guided visualization activity on the re-construction of participants’ perceptions of teacher identity. The interdisciplinary theoretical orientation was grounded in theories and concepts from psychology and educational research, e.g., Personal Construct Theory (Kelly, 1955, 1963), the complementary nature of reason and intuition, and the concept of “perspective transformation” (Mezirow, 1978, 2000). The methodology was heuristic research (Moustakas, 1990, 1994) and methods included reflexive autobiographical journaling, guided visualization, and in-depth interviews. The results confirm that teacher identity is deeply embedded in one’s personal biography. Participants’ beliefs, perceptions, and interpretations nurtured in the family environment strongly influenced their school experiences, career choice, instructional practice, teaching philosophy, and teacher identity. The use of the guided visualization technique, integrated with rational reflection, considerably enhanced the depth and breadth of participants’ self-understanding and personal/professional growth, which is an important methodological contribution of the study for teacher development. The results strongly suggest that it is essential to explore teachers’ personal life experiences in order to gain a holistic understanding of the dominant influences on the development of teacher identity. The study presents a model for designing a longitudinal professional development program offered in a series of workshops to raise teachers’ awareness of the implicit influences on teacher identity and instructional practice through the application of both conscious/rational and intuitive/tacit methods to access their beliefs, perceptions, and interpretations of their life experiences.

This paper deals step by step with process of stitching images taken by perspective camera rotated by its optical center into the panoramic image. There are described keypoint searching algorhytms, possibilities of calculating homography matrix and methods of eliminating unwanted seams between source images in final panoramic image. A part of this paper is also standalone application in which are implemented some algorhytms described in the work.

The diploma thesis is focused on the topic of transformative learning in connection with adult experiential learning. The goal of the thesis is to identify transformative effects in the interpretation of participants' experiences which are caused by experiential learning courses. The concept of transformative learning is mainly examined by foreign authors who look at the concept from different perspectives. This thesis deals with a qualitative survey which is based on the reflection of the common framework of transformative learning, including its various concepts and topic of adult experiential learning. Respondents of the survey are nine employees in management positions who have completed a long-term development program focused on management skills. The development of semi-structured interview with respondents was aimed at identifying a shift in "knowing" and changes in thinking, perception and action throughout life. The analysis of qualitative data brings concrete implications in the interpretation of experience in work and personal life.

Dans un contexte social où se renégocie le contrat de genre, l’exploration des voies empruntées par les hommes pour (apprendre à) changer leur comportement, aussi bien que leurs croyances et leurs connaissances sur la masculinité, est particulièrement importante. Située dans le champ des études sur le genre masculin et de l’andragogie, l’étude explore le processus d’apprentissage d’adultes faisant partie du Réseau Hommes Québec (RHQ). En utilisant une méthodologie qualitative, des entretiens semi-dirigés ont été effectués auprès de 16 membres de cette organisation d’entraide visant la remise en question des rôles de genre traditionnels masculins et encourageant le développement personnel des hommes. Si la plupart des répondants n’ont pas transformé radicalement leur conception de la masculinité, qui demeure souvent abstraite, leur façon de se voir comme homme a changé radicalement. Les émotions et les relations ont joué un rôle prépondérant dans le développement d’une réflexion critique sur le genre, le leur comme celui des autres. Le plus souvent, ils ont eu le courage de sentir, d’être et d’agir de façon inédite avec d’autres hommes. Cela a représenté, pour pratiquement tous les répondants, une véritable révolution intérieure qui leur a fait prendre conscience qu’ils étaient sensibles, qu’ils avaient besoin d’autrui et qu’ils pouvaient approcher d’autres hommes sans que leur orientation (hétéro)sexuelle soit menacée. Cette thèse met également en perspective que le contexte de groupe est crucial dans l’évolution des hommes. La socialisation masculine inédite vécue dans le Réseau favorise chez tous les répondants la découverte de modèles de masculinité différents. En plus d’y vivre des occasions uniques de développer des compétences relationnelles, sociales et communicationnelles qui les rapprochent de leurs proches, les répondants éprouvent dans les groupes du RHQ un sentiment puissant de pouvoir partager de l’intimité masculine. Ce nouveau mode d’interaction s’appuie sur les règles de fonctionnement et les rituels en vigueur dans le Réseau. Ils mettent l’accent sur la nature personnelle et subjective de la communication, défiant en cela les préceptes de la masculinité traditionnelle. En mettant en évidence que les hommes développent une conscience critique permettant de reconnaître et de comprendre l’importance de la culture masculine hégémonique et son impact sur leur vie, cette recherche révèle le potentiel transformationnel des apprentissages effectués par les 16 répondants dans des groupes d’entraide du RHQ. De cette conscientisation résulte une nouvelle conceptualisation de ce que signifie être un homme qui mène les participants à se voir autrement, à croire en eux-mêmes et en leur capacité à prendre le contrôle de leur vie. Pour conclure cette thèse, quelques pistes de réflexion pour guider de futures recherches relatives à la transformation de perspective sont présentées. Il est notamment question, en plus d’avoir recours à des entretiens rétrospectifs semi-dirigés, de combiner les méthodologies qualitatives et quantitatives, de procéder à des observations systématiques des situations d’apprentissage (rencontres de groupe) et de ne pas se concentrer exclusivement sur ceux qui sont supposés vivre la transformation, mais d’élargir cette collecte à d’autres sources d’information (familles, collègues de travail, voisins, thérapeutes individuels), le tout dans une perspective longitudinale. / In a social context where gender conventions are renegotiated, the exploration of ways taken by men to (learn to) change their behavior, as well as their beliefs and knowledge of masculinity, is particularly important. Situated in the fields of Men’s Studies and adult education, the study explores the learning process of adults being part of the “Réseau Hommes Québec” (RHQ). Using qualitative analysis methodology, semi-directed interviews were conducted with 16 members of this mutual aid organization aiming on the question of masculine traditional gender roles and encouraging the personal development of men. If most of the interviewees have not thoroughly transformed their conception of masculinity, which often remains abstract, their way to conceive themselves as men has changed radically. Emotions and relations have played a predominant role in the development of a critical reflection on gender, on their part as well as on others’. Most often, they had the courage to feel, to be and to act in an unobserved way with other men. This represented, for practically every interviewee, a real internal revolution making them realize that they were sensitive, that they needed others, and that they could get close to other men without threatening their own (hetero) sexual orientation. This thesis equally brings in perspective that the group context is a crucial element permitting men to evolve progressively. The unseen masculine socialization experienced in the Réseau (RHQ) has allowed all of the interviewees to discover different masculinity models. As well as offering them unique opportunities to develop relational, social, and communicational skills which promote harmony with their close ones, the RHQ groups have permitted the interviewees to experience a feeling of communitas, an impression of sharing masculine intimacy. This new interaction mode depends on regulations and rites in effect within the RHQ. They emphasize the personal and subjective nature of communication, challenging therein the traditional masculinity precepts. In intensifying that men develop a critical conscience allowing them to recognize and understand the importance of hegemonic masculine culture and its impact on their lives, this research reveals the potential of transformational learning performed by the 16 interviewees in the RHQ support groups for men. From this awareness will result a new conceptualization of being a man that will lead participants to perceive themselves otherwise, to believe in themselves as in their capacity to take control over their own lives. Finally, new reflection avenues are presented to guide future research related to perspective transformation. Notably, it is proposed that as well as having recourse to semi-directed retrospective interviews, to combine qualitative and quantitative methodology, to proceed with systematic observation of learning situations (group meetings), and to avoid concentrating exclusively on those who supposedly underwent the transformation, but to widen this data collect to other sources of information (family, work colleagues, neighbors, individual therapists), all in a enlarged perspective.
