Estimating Previous Quantization Factors on Multiple JPEG Compressed Images

Abstract The JPEG compression algorithm has proven to be efficient in saving storage and preserving image quality thus becoming extremely popular. On the other hand, the overall process leaves traces into encoded signals which are typically exploited for forensic purposes: for instance, the compress...
