Detecting Non-aligned Double JPEG Compression Based on Refined Intensity Difference and Calibrationpropose a novel feature set to detect NA-DJPEG compression based on refined intensity difference (RID), a new measure for blocking artifacts. Refined intensity difference is essentially intensity difference with compensation, which takes the negative effect of image texture into consideration when m
