The Analysis and Detection of Double JPEG2000 Compression Based on Statistical Characterization of DWT Coefficients
Detection of double image compression is all the world to the analysis of tampered image and image steganalysis. In order to detect double JPEG2000 compression, through the comparison with JPEG double compression, we analysis the different statistical characterization of DWT coefficients frequency histogram under single and double compression because of post compression rate distortion optimization ( PCRD-opt algorithm ) in JPEG2000 codec. We find a new statistical characterization which is different form double JPEG compression. Under certain conditions, experimental results show that such features can be used to detect whether the JPEG2000 image is double compressed or not
