traitement d images contours et formes

说明：  主成分分析算法提取特征值，使用KNN分类器，K值可调(principal component analysis)

图像拼接技术，图像配准技术，初步实现有重合区域的两幅图像的配准(Image mosaic technology, image registration, the initial overlap region to achieve a registration of two images)

使用matlab实现的小波变换彩色图像水印嵌入和提取程序(Realize the use of matlab wavelet transform color image watermark embedding and extraction procedures)

matlab环境下 建立单高斯模型，检测出运动的人体，后期经过数学形态学处理，效果很好。(matlab environment to establish a single Gaussian model, to detect the movement of the human body, the latter mathematical morphology after treatment, the effect well.)

说明：  为了达到较好的隐藏效果，本文采用游程编码的方法在二值图像中隐藏信息。秘密信息嵌入时修改二值图像的游程长度，如果秘密信息为是0，则修改该游程长度为偶数；如果秘密信息的取值与游程长度的奇偶性相匹配，则不改变游程长度。提取时根据游程长度奇偶性提取出秘密信息。在信息隐藏时，改变游程的奇偶性时通过对下一个游程的第一个像素值进行修改，因此当下一个游程长度为1时通过改变当前有成的值实现。(In order to achieve better hiding effect, we use run length encoding method to hide information in two value images. When the secret information is embedded, the length of the travel length of the two value image is modified. If the secret information is 0, the length of the travel length is even even. If the value of the secret information is matched with the parity of the length of the run, the length of the journey is not changed. The secret information is extracted according to the parity of run length. In information hiding, changing the parity of the journey is modified by the first pixel value of the next run, so the current length is 1 by changing the current value.)

可根据需要自定义窗口形状，用于各种特效窗口开发(Customizable window shape, for a variety of special effects needed to develop window)

同态滤波函数：使用频域处理方法的同态滤波函数，非高斯，巴特沃斯或指数型。对于较黑的图像效果更好(Homomorphic filtering function: the use of frequency domain methods of treatment homomorphic filtering function, non-Gaussian, Butterworth, or index. For more images and better)

通过腐蚀，去轮廓等操作去除图像背景，适合matlab初学者认识程序。(Corrosion, go to outline operation to remove the image background for Matlab beginners understanding of the program.)

基于窄带法编写的水平集函数，要先手动选择初始轮廓。(narrowband_CV model)
