FAST AND ROBUST IDENTIFICATION METHODS FOR JPEG-CODED IMAGES(International Workshop on Advanced Image Technology 2006)

概要

論文の詳細を見る
We propose two identification methods for JPEG-coded images. The purposes are to identify the images in fast and robust manner. Robust identification refers to ability of the methods to identify the JPEG images that are generated from the same original image and have equivalent or different compression ratios without leakage or false negative (FN) and false positive (FP). The first approach can avoid identification leakage, and could result in a few false positives (FP). The second approach can avoid both FN and FP, with a slightly longer processing time. By combining the two schemes, a faster and a more perfect identification can be achieved, in which FN and FP can be avoided.
