Blind detection of the doctored JPEG image based on the inconsistencies of quantization table
基于量化表不一致性的JPEG图像篡改盲检测

A new approach is proposed to detect JPEG image forgery through the inconsistencies of quantization table.The original quantization table is estimated iteratively by selecting qualified blocks intelligently and further used to position the approximately doctored areas.Then the doctored area is compressed by the original quantization table estimated.Using the difference between the double compressed image and the test image,doctored areas will be more precisely determined.Simulation results show that the qua...
