In order to extract from the video sequence in a complete and consistent moving target, a novel algorithm for video object segmentation based on improved particle swarm optimization (IPSO) is presented. The algorithm fuses brightness segmentation and color information at `region level', as to make up for conventional `pixel level' approaches. The IPSO is taken into account for spatial segmentation...
Key frame extraction technique plays an important role in video analysis and content-based video retrieval. Key frame has been used to reduce the use of video indexing data greatly and it also provides a framework to video summaries and retrieval. This paper proposes a novel method based on invariant moments for key frame extraction, according to the changes of independent objectpsilas shape and brightness...
