The proposed algorithm including the customized NCC was implemented and tested using Matlab 2014a tool. Several experiments are conducted for evaluating the performance of the proposed algorithm under different parameter settings, like IJc, coarse block size, the degree of overlapping etc. The experiments were performed on the dataset available at31 for image forensics. The dataset consists of ten original JPEG color images and their copy move forged versions. The following results show that the proposed algorithm detects the copied and the pasted regions successfully. The block size chosen was 20 and step size chosen was 4, and the threshold IJc and IJf both for the coarse forgery detection and Fine-tuned forgery detection was 0.98. It can be noted from the result that the algorithm is capable of detecting the pasted regions even when they are more than one in the same image. The computational time taken for processing the image and detecting the forgery is found to be less as compared to the lexicographic sorting based algorithms in the literature. Figure 1 shows the results obtained by the proposed method.
