Abstract:
Cet article aborde les relations entre le langage visuel et les émotions. Cette exploration se compose de deux volets : le premier est consacré aux forces textualisées dans l’image, le second aux gestualités émotionnelles, à savoir aux pratiques énonciatives du corps qui accompagnent l’interprétation et l’appréciation des images. La première partie discute la contribution de René Thom à la réflexion sur les émotions de la contemplation esthétique face au déploiement des forces dans les tableaux ; tandis que la deuxième partie met en contraste l’analyse manuelle et l’analyse computationnelle au

Abstract:
Visual performance is defined as the speed and accuracy of processing visual information. Existing models of visual performance evaluate illuminated tasks in terms of luminance contrast, retinal illuminance and visual size but do not consider the chromatic properties of the task. In consequence, there is no recommendation for the chromatic contrast needed to reach a high level of visual performance. This paper shows that chromatic information is crucial to visual performance when achromatic information is weak or missing altogether. When the luminance contrast is less than approximately 0.20,

Abstract:
Ce travail étudiait les influences réciproques entre l'état émotionnel et la perception visuelle – notamment celle du contraste de luminance –, dans un modèle de déficit émotionnel: l'anhédonie. Nous avons montré chez des sujets anhédoniques une diminution du plaisir face à des images émotionnelles à différents niveaux de contraste, et selon les tests psychophysiques, une meilleure sensibilité au contraste. L'étude de l'activité cérébrale en IRM fonctionnelle suggère qu'il existe chez les anhédoniques un excès d'amplification de l'activité des aires visuelles en réponse aux stimuli positifs pa

Abstract:
System operation contracts were introduced by C. Larman as an application of the notion of Design by Contract (DbC) to the description of high-level system operations derived from requirements. A system operation contract specifies an operation in terms of changes induced in the domain. In the Responsibility Driven Development (RDD) process proposed by Larman, operation contracts play an important role in identifying and assigning systems' responsibilities, and help construct a sound design in later phases. Larman's notation for operation contracts is textual. In this thesis, we propose an alt
