Texture discriminability in monkey inferotemporal cortex predicts human texture perception

Texture discriminability in monkey inferotemporal cortex predicts human texture perception

Shape and texture are both important properties of visual objects, but texture is relatively less understood. Here, we characterized neuronal responses to discrete textures in monkey inferotemporal (IT) cortex and asked whether they can explain classic findings in human texture perception. We focused on three classic findings on texture discrimination: 1) it can be easy or hard depending on the...

Human versus artificial texture perception

Texture 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...

Texture, human perception, and information retrieval measures

Content-based image retrieval (CBIR) uses image properties such as colour, texture and shape. Although colour has been used successfully, texture can be even more significant, both for human perception and for CBIR. We present the results from a human study with 30 volunteers that ranks the “most like” images for each of the Brodatz textures. In all cases, only a limited number of the other tex...

The orientational resolution of human texture perception

A major determinant of human texture segregation and discrimination is the orientational content of the stimuli used. We have investigated the ability of observers to resolve features defined in the orientation domain in a variety of textures. It was found that features had to be separated by at least 13 deg for subjects to discriminate orientationally bimodal textures from same-variance unimod...
