摘要：
JPEG (Joint Photographic Experts Group) algorithm is widely used in imaging system. When image data are highly compressed by JPEG, the image is deteriorated. Deterioration of false contour and mosquito noise is mainly felt. In the restoration, false contour area is extracted and is smoothed by fitting method of least squares algorithm. Improved result is obtained, compared with the former method proposed by us.
