Choosing wavelet pairs in supression of illumination variations for port surveillance

In order to implement visual surveillance system, many problems have to be considered. Paper deals with one of them, illumination variations. Illumination variations, in the stream, produce additive noise which could cause false motion detection. To overcome the problem, wavelet motion detection algorithm based on energy minimization has been considered. It is important to notice, in order to get an efficient algorithm, it is required to devise a method for choosing wavelets. The method covers correct detection and processing time.
