The use of filters is one of the major techniques for texture feature
In this paper, we present approaches to filter design for optimal texture
A generic feature extraction scheme of a finite
impulse response filter and a local energy function is modelled, and the
filter is optimized with respect to the Fisher criterion.
We develop the necessary expressions for a gradient search optimization.
Based on some assumptions, we also find a closed form solution to the
Then we extend the closed form solution to a more generalized unifying
Finally, the practical utilities of the filter design techniques are shown
