Abstract
Based on the differences of pattern noise between real images and computer images, this paper advanced a new method which combined the SNR features with the higher order characteristics of the predicting error images. Where the SNR features consist of MSE, SNR and PSNR features between original images and modified images which were got by add-noising and de-noising for the original images. Experimental results show that this algorithm´s recognition rate can get 94.33% in the Columbia Image Dataset [1].
