Abstract :
In this paper we introduce a new image model called MSEC (Multi-Scale Edge Compensation) and implement an image compression system based on MSEC. MSEC consists of semantically meaningful components including edges of different types and scales, and the background. The MSEC-based image coding technique permits some image analysis operations such as edge detection, enhancement, and content-based retrieval to be carried out directly in the compression domain
