The role of co-circularity of local elements in texture perception.
The present study analyzes the effect of local pairwise orientation relations on the perception of textural structure. We have employed a new class of stochastic stimuli comprised of paired Gabor patches with a particular orientation difference (theta) and relative angular position (phi). We measured the threshold proportion of signal pairs for discriminating the target texture from a noise tex...
متن کاملTarget-selective tilt aftereffect during texture learning
In texture learning, observers are presented with repeated stimulations, resulting in within-day threshold elevation, as well as between day threshold reductions. Within-day deteriorations were shown to be location and orientation specific (Mednick et. al., 2002; Ofen et al., 2007). Accordingly, the declined performance was suggested to reflect sensory adaptation. Here we test whether extensive...
متن کاملTexture perception
As we parse the retinal image into different objects, a number of visual properties are used to distinguish figure from ground and one object from neighboring objects. These properties include luminance, color, relative motion, and stereo disparity. Within a single surface there can be variation in surface reflectance, color, or three-dimensional orientation (surface roughness). These variation...
متن کاملVisual aftereffect of texture density contigent on color of frame.
An aftereffect of perceived texture density contingent on the color of a surrounding region is reported. In a series of experiments, participants were adapted, with fixation, to stimuli in which the relative density of two achromatic texture regions was perfectly correlated with the color presented in a surrounding region. Following adaptation, the perceived relative density of the two regions ...
متن کاملPerceptual asymmetry in texture perception.
A fundamental property of human visual perception is our ability to distinguish between textures. A concerted effort has been made to account for texture segregation in terms of linear spatial filter models and their nonlinear extensions. However, for certain texture pairs the ease of discrimination changes when the role of figure and ground are reversed. This asymmetry poses a problem for both...
