Nonlinear operator for oriented texture
Texture is an important part of the visual world of animals and humans and their visual systems successfully detect, discriminate, and segment texture. Relatively recently progress was made concerning structures in the brain that are presumably responsible for texture processing. Neurophysiologists reported on the discovery of a new type of orientation selective neuron in areas V1 and V2 of the...

Texture is an important part of the visual world of animals and men and their visual systems successfully detect, discriminate and segment texture. Relatively recently progress was made concerning structures in the brain which are presumably responsible for texture processing. Von der Heydt et al. (von der Heydt et al. 1992) reported on the discovery of a texture processing neuron in areas V1 a...
متن کاملGrating cell operator features for oriented texture segmentation
The performance of two well-known texture operators (based on Gabor-energy and the cooccurrence matrix) is compared with the performance of a new, biologically motivated texture operator, the grating cell operator, which was proposed elsewhere by the authors. The comparison is made using a new quantitative method, based on the Fisher criterion. Together with some classification results comparis...
متن کاملNonlinear Texture Mapping Techniques For
S As graphics hardware is available on most PCs these days, hardware-assisted real-time rendering becomes more important in many applications, such as games or virtual reality. Texture mapping is also important in graphics rendering, because it gives much visual detail without modeling of complex geometry. Conventional texture mapping by graphics hardware relies on the linear interpolations of ...
متن کاملTexture Edge Detection Using the Compass Operator
The compass operator has proven to be a useful tool for the detection of color edges in real images. Its fundamental contribution is the comparison of oriented distributions of image features over a local area at each pixel. This paper presents extensions and modifications to the operator to make it applicable to texture edge detection in high dimensional images whose dimensions represent the o...
