Firstly,a wavelet homonorphic filtering is applied to enhance the high frequency edges after the blurring process. Secondly,the natural edges are eroded by mathematical morphology method,then the enhanced artifical blur edges are preserved.
针对伪造图像中常用的模糊操作,提出一种伪造图像的检测方法,该方法首先对伪造图像进行小波域同态滤波,增强处于高频段的人为模糊边缘,然后利用数学形态方法腐蚀掉自然边缘,保留增强的模糊边缘,最后对腐蚀后的边缘图像进行区域标定,从而定位出伪造区域。
