Abstract

In this paper, we proposed a method to detect splicing forgery by using wavelet transform and background noise estimation in digital image. To achieve this target, we divide image into some sub-blocks and use wavelet transform to extract the low-frequency sub-band coefficients of each ones. Then, the noise standard deviation in each bands can be estimated with the statistical properties of skewness. In the end, the morphological marker is used to tamper with the region. Comparisons with existing methods by experiments showed that our proposed method is effective in estimating the noise standard deviation, and has high accuracy in detecting and localizing forgery parts especially in local smooth regions.
