代码说明:

  JSteg隐写技术matlab实现代码--基本思想:用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位,但若量化后DCT系数为0或者1,则不进行处理。(DCT系数的LSB嵌入) (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))

  • Advanced_extracting_algorithm_for_edge_feature_poi
    : 对一种基于图像几何重心的特征点提取算法进行了改进 改进后的算法可以提取任何边缘线上凹凸处的特征点 其基本 思想是,首先提取图像的边缘轮廓线,计算封闭边缘线和非封闭边缘线的几何重心 然后以重心为极点,对边缘点极坐标化,形成 幅角-极径曲线,在该曲线上寻找局部极大极小值点 最后根据局部非极大(小)抑制原则对极大(小)值点进行取舍获得特征点 模 拟结果表明算法计算简单 稳定性好 该方法提取的特征点能准确地反映目标的形状,对目标的识别 跟踪以及三维表面重建等都 具有重要的价值(This paper modifiesakindoffeatureextractingalgorithmbasedonimageedge.First, imageedgeoutlineisextracted.
