Abstract

The JPEG (joint photographic experts group) compression algorithm is possible to decode an image effectively, by considering the visual characteristic of human beings. The mosquito noise generates in the block, when a compression rate of the JPEG is high. On the other hand, the block noise is not generated in the JPEG2000 decoded image because an algorithm of the JPEG2000 based on DWT (discrete wavelet transform). However, the mosquito noise appears to a high compressed image by using the JPEG2000. We lose not only the mosquito noise but also some important image information, when the usual noise reduction filter is applied for a JPEG/JPEG2000 decoded image including the mosquito noise. As a result, the image quality worsens.In this paper, we propose an efficient algorithm which reduces the mosquito noise of the JPEG/JPEG2000 decoded image by using ε-filter. We confirmed that our proposed method was effective by the computer experiments.
