Estimation method of mosquito noise in JPEG image based on cepstrum analysis

Abstract

JPEG images include a visual distortion which is called the mosquito noise around edge region. It is difficult to estimate the mosquito noise from a given encoded image, since the visual effect is dependent with the characteristics of each input image. This paper presents an estimation method of the mosquito noise based on the cepstrum analysis. It is seen in our experimental results that the period and the intensity are relationship with the peak of the cepstrum coefficients.
