Fractal Video Compression using Block Matching Motion Estimation - A Study
نویسنده
چکیده
The large usage of multimedia applications on internet and mobiles has increased the demand of compressed data, as to reduce the bandwidth requirement and transmission time. So block based method for video compression is getting more importance due to its effectiveness and easy implementation. Fractal video compression follows the property of self-similarity. The weighted finite automata exploits the property of selfsimilarity in a single image or sequence of images. In block matching motion estimation various algorithm has been proposed having different search pattern and strategies. The paper presents the review on different methods for fractal video compression.

In this paper we introduce two techniques that can be used together to improve video coding performance. Firstly, block matching motion estimation with spatial transformation (BMST) is used to increase motion compression eeciency, and then motion compensated prediction (MCP) errors are encoded using a hybrid Fractal/DCT scheme. MCP error blocks are classiied according to their energy content an...
