Psychophysical study of image orientation perception

Psychophysical study of image orientation perception

The experiment reported here investigates the perception of orientation of color photographic images. A collection of 1000 images (mix of professional photos and consumer snapshots) was used in this study. Each image was examined by at least five observers and shown at varying resolutions. At each resolution, observers were asked to indicate the image orientation, the level of confidence, and t...

Psychophysical study of LCD motion-blur perception

Motion-blur is still an important issue on liquid crystal displays (LCD). In the last years, efforts have been done in the characterization and the measurement of this artifact. These methods permit to picture the blurred profile of a moving edge, according to the scrolling speed and to the gray-to-gray transition considered. However, other aspects should be taken in account in order to underst...

Psychophysical Measurement of Odor Perception in Humans

Explaining the Model of Eevaluative Image in the Perception of the Environment (Case study, Bushehr city)

Aims & Backgrounds: In today's competitive world, cities are increasingly concerned about their identity, image and value, In this regard, creating an environment favorable to attracting different classes of the ambitions of city managers and planners in each city. This can only be achieved what the city presents (identity), what is perceived (image) and its evaluation by its users (the evaluat...

Visual imagery facilitates visual perception: psychophysical evidence.

Visual imagery is the invention or recreation of a perceptual experience in the absence of retinal input.The degree to which the same neural representations are involved in both visual imagery and visual perception is unclear. Previous studies have shown that visual imagery interferes with perception (Perky effect). We report here psychophysical data showing a direct facilitatory effect of visu...
