摘要

Abstract: Objects and camera movements are important clues, which can be used for a better video and image understanding for content-based image and video indexing. In this paper, we propose a new general technique for object and 3D camera movement detection based on 2D hints extracted from 2D images. Our approach consists of extracting first 2D hints based on object contours and calculating their different order derivatives. We then apply our pattern matching method to obtain objects movement vectors, and with help of 3D projection theory, we detect the camera movement description in the 3D space. The further work we have been undertaking shows that 2D and 3D hints combined with movement vectors can lead to 3D scene description. Some experimental evidence is also provided. !13
