A Long Term Change Detection (CD) Method is presented by definition of a probabilistic-model and the integration of two different informative sources. The model is described from a theoretical point of view and its real implementation by means of a bank of shift registers is presented. The algorithm is part of a surveillance system for...

he research in the field of Advanced Video-based Surveillance (AVS) Systems is significantly increased in the last few years, mainly thanks to the greater opportunities offered by the tremendous rate of innovation in computer and communication technologies.

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...
