代码说明:

  对图像进行逐点计算,并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时,首先确定一个阈值T,若图像中像素点的新 值大于该门限值,则可以初步确定为边缘点,小于T的新值被判断为非边缘点.(Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.)

    dct隐写技术matlab实现资料。算法原理:通过在一个图像块中调整两个DCT系数的相对大小,隐藏秘密信息。 将载体图像分为8×8的块,做二维DCT变换 用来表示选中的两个系数的坐标对于第i bit秘密信息 if(要隐藏信息‘1’) make else make 逆DCT变换,还原图像 (dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)
