Jsteg
Jsteg算法实现,Jsteg是一种基于JPEG的常用信息隐藏算法步骤如下:
首先,把掩体图像分为不重叠的8*8的子块,对每一子块进行DCT并对变换得到的DCT系数进行量化 其次,将待隐藏的信息进行加密,将加密结果嵌入到量化后值不为0,1或-1的DCT系数的最
低有效位(LSB)中,其嵌入顺序是按zigzag扫描顺序进行的。最后,用JPEG的嫡编码(包括哈夫曼编码,游程编码及DPCM)对嵌入秘密信息后的每一子块进行编码,从而得到一个含有秘密信息的JPEG stego文件。(Jsteg Algorithm)

双峰法是一种简单的阈值分割方法,即如果灰度级直方图呈现明显的双峰状,则选双峰之间的谷底所对应的灰度级作为阈值分割。(Two peaks is a simple threshold segmentation method, that is, if the gray level histogram showed a clear bimodal shape, then choose between the two peaks corresponding to the bottom of the gray level as threshold segmentation.)

meanshift-tracking
主要思想是用meanshift算法跟踪目标,拖动矩形框选择目标模板,meanshift自动跟踪
本程序的主要缺陷体现在帧差法自动识别目标,这部分功能与上一个功能独立,可用可不用,用于自动识别目标,效果不是很好,主要体现在对图像视频的要求是 背景(目标以外的所有事物)不能动(The main idea is to use meanshift algorithm to track the target and drag a rectangle to select the target template, meanshift automatic tracking
The main drawback of the program is reflected in the frame difference method automatically identifies the target, which is part of the function and one function independently, may or may not, be used to automatically identify the target, the effect is not very good, mainly reflected in the requirements of the video image is the background (target All things outside) can not move)
