JPEG images are degraded by blocking artifacts and mosquito noise caused by quantization on the block DCT domain. The purpose of this paper is reduction of image quality degradation by means of the image restoration method instead of the smoothing method after the simple decoding. This proposed method is based on the edge-adaptive restoration method; the regularizing operator depends on the edge orientation, and the regularizing parameter depends on the local activity. The variance of the quantization on the block DCT domain is taken into consideration.
