Abstract

The major artifacts of JPEG compressed images are blocking and ringing, which are mainly due to the quantization of low frequency and high frequency DCT components respectively. The ringing artifacts are particularly dominant in document images, where sharp edges present commonly in text and graphics are more likely to be encountered. In this paper we describe a decompression algorithm with reduction in both ringing and blocking artifacts.
