Abstract

It is always a big challenge to extract moving objects in complex video scenes because bad weather or dynamic backgrounds can seriously influence the results of motion detection. In this research, a new hybrid approach combining independent component analysis (ICA) with principal component analysis (PCA) is proposed for multiple moving objects extraction in complex scenes. First, a fast ICA algorithm is used to analyze the optical flows of video frames, so that the optical flows of background and foreground can be approximately separated. Next, the PCA is applied to the optical flows of foreground components as such the major optical flows corresponding to target multi-objects can be extracted accurately and the motions resulting from changing backgrounds are cleared away simultaneously. Preliminary experimental results demonstrate that the proposed novel hybrid ICA and PCA-based approach can extract multiple objects effectively in a complex scene.
