Study On Technology Of Objects Retrieval From Video Image

This paper is about study on technology of objects retrieval from video image. It involves moving objects detection and retrieval under a static background.On the research of moving objects detection and retrieval under a static background, the popular technology of video image segmentation is discussed briefly and then theory model of moving objects detection and segmentation is proposed. Based on adjacent frame difference, we proposed a improved algorithm. An experiment result was given to show this method is efficient.When we want to segment the objects in the video image, the analysis only on objects region is not enough and not all useful information in the video image is made the most of. An algorithm based on adaptive background restoring subtraction is proposed. This algorithm can works efficiently in real time when background is unknown.
