Performance Evaluation of CMFD Algorithms Using DCT and SIFT over Different Color Spaces

Abstract

Image Forgery is one of the major concerns in today's Digital World because of availability of advanced photo editing tools. Different methods are available in the literature for detection of various image tampering methods, but work for forgery detections using color space is not much explored. The existing methods mainly use the gray scale images for forgery detection. However, the color information of image is important for the object detection and matching tasks. In this paper we propose an approach of considering the color channel of color model along with features for detection of image tampering.
