Abstract:

 Focusing on the face stitching tampering image, a splicing image tamper detection method based on human face color temperature was proposed. Using the technology of target detection, the method in question pinpointed the faces in the image, and then estimated the color temperature of all those faces and the reference color temperature. After calculating the discrepancy between human face color temperature and reference color temperature, the method could find out the detection target with abnormal color temperature discrepancy as the tampering target, and then could locate the precise position of the tampering target. The empirical study showed that the algorithm was effective.

Key words: reference color temperature;color temperature discrepancy, image tamper detection, human face color temperature, face stitching, target detection
