Recognition-based tracking and image coding methods are often based on different techniques. However, these techniques share the necessity of reliable and fast methods for the representation of the information content of the scene. In this paper, a method based on a lossy shape descriptor is presented which can be used for both recognition and...

A non-linear digital filter is presented in this paper: this filter aims at extending the concept of scalar rank-ordering in the case of multichannel images. The filter is based on two steps: (1) a transformation from a p-dimensional steps to a one-dimensional space by means of a space filling curve; (2) a scalar median filtering step. Results...
