  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)

  • ACOR
    Ant Colony Optimization (ACO) is an optimization metaheuristic based on the foraging behavior of ants. This metaheuristic was originally proposed to find good solutions to discrete combinatorial problems. Many extensions of the ACO heuristic for continuous domain have been proposed, but even those that claim close similarity with classical (discrete domain) ACO, like ACOR, do not use the heuristic information called visibility, commonly used in the original ACO algorithm. In this paper, we show the importance of the visibility in ACO, by proposing ACOℝ -V , a variant of ACOR that performs better in a number of benchmark functions.
