一种适用于有损压缩图像的重采样检测算法
Resampling Detection Algorithm for Lossy Compression Image
摘要
Abstract
The similar statistical properties between pixels in lossy compression and resampling operation makes the lossy compression image hard to detection. In order to solve the problem, this paper presents a resampling detection algorithm which is applied to lossless compression. It investigates the spectrum characteristics of an image by analyzing the periodicity of interpolating signal and then estimate interpolation coefficient of the image resampling. Experimental results indicate that this algorithm has strong robustness and wide application, and it has precision rate for JPEG lossy compression image resampling detection.关键词
