An adaptive wavelet shrinkage based accumulative frame differencing model for motion segmentation

Abstract

Motion segmentation in real-world scenes is a fundamental component in computer vision. There exists a variety of motion recognition algorithms, each with varying degrees of accuracy and computational complexity. The most widely used techniques, in the case of static cameras, are those based on frame difference. Those methods have a significant weakness when it comes to detect slow moving objects. Therefore, we introduce in this paper a novel approach that aims to improve motion segmentation by proposing an accumulative wavelet based frame differencing technique. Moreover, in the proposed approach we exploit a combination of several techniques to efficiently enhance the quality of motion segmentation results. The approach's performance on real-world video sequences shows that comparing frames using the 2D wavelet transform increases motion segmentation quality.
