摘要
针对人脸合成图像进行真假鉴别,定量计算人脸边缘处的梯度幅值和纹理对比度,以及通过对肤色进行色度、饱和度分析,对图像的真假进行判断。实验结果表明,文中方法简单,效果良好。
A new method for detecting the face synthetic images is proposed.The quantitative calculation of edge intensity and texture contrast values and hue and saturation analysis for skin color are adopted in the proposed method to judge the authenticity of the image.The experimental results show the efficiency of the proposed simple method here.
