This work presents an analytical design method for a category of two-dimensional IIR filters,
specifically with circular symmetry, which have useful applications in image processing. The …

This work proposes an analytic design method for a particular class of 2D filter banks, with
circular shape in the frequency plane and a maximally-flat characteristic. The circular filters …

In this work an efficient analytic design method for 2D zero-phase circular filter banks is
described. They are obtained from 1D prototype filters with specified bandwidth, to which a …

This paper proposes an analytical design method for 2D zero-phase recursive filters with a
circularly-symmetric frequency response. The design is based on a maximally-flat low-pass …

This paper approaches an analytical design method for a type of 2D band-pass circularly-
symmetric Gaussian-shaped recursive filters. The method is based on a Gaussian prototype …

In image processing, micro-textures are generally represented as homogeneous random
fields, the term" homogeneous" indicating a second-order stationary random process …

A feature point is a salient point which can be separated from its neighborhood. Widely used
definitions assume that feature points are corners. However, some non-feature points also …
