Abstract

We propose a new method for detecting changes in the scene structure. The detection is based on the evaluation of amount of changes in data acquired from the environment and on the character of these changes. We propose a concept of Short-time Independent Component Analysis and a metrics for comparison of two Generalized Gaussian mixture ICA models.
