Abstract:

Nowadays, malicious tampering and forgery images show an explosive growth trend. The existing image tampering detection methods generally have the problems of single application scope and low detection accuracy. To solve these problems, this paper proposes a tampering and forgery image classification detection network based on image texture features. For the first time, it combines the first step edge texture image of Cb and Cr channel through Scharr operator with the second step edge texture image of G channel through Laplacian operator. Gray Level Co-occurrence Matrix (GLCM) is used to extract the features of texture image. Finally, the tampering and forgery are monitored by EfficientNet. Experiments on various image tampering and deep forgery datasets show that the model has wide applicability and high detection accuracy in both types of detection, and the classification detection accuracy of images generated by various Deepfake algorithms can reach 99.9%.
