Paper Abstract

Video Mosaicing is the process of obtaining single unified picture from multiple frames of a video sequence. It involves finding the geometric transformation parameters between frames and aligning them to form a single image representing content of full video. The proposed mosaicing method takes advantage of the information encoded by MPEG in the form of motion vectors, DCT blocks and the error information for generating the mosaics. Only the motion vectors corresponding to blocks of high activity region are considered for finding affine parameters. The feasibility of the method has been tested on panorama views from various MPEG sequences. The performance of proposed method was evaluated against the existing uncompressed domain methods.
