PCNN 灰度图像，图像分割matlab程序(PCNN_GrayImage_Segmentation)

选择一副灰度图像，用区域分裂合并法对其进行分割(Choose a grayscale image, with its regional divisions split merge method)

于轻小型光学成像系统，小孔径限制了 图像的极限分辨率，衍射退化造成了截止频率外信息的丢失成像系统所期望的 大视场不可避免的带来边缘视场的像差恶化，各视场退化情况不同，影响信息的 判读 (Small light optical imaging system, the small aperture limit the ultimate resolution of the image, diffraction degradation aberration deterioration of the desired cutoff frequency outside the loss of information imaging system field of view inevitably bring the edge of the visual field, each referred to as field degradation, affecting the interpretation of the information)

说明：  利用小波进行边缘提取，比较各种小波核函数的能力，体会“数学显微镜”的妙用，例子：车牌定位。(using wavelet edge detection, comparison of different wavelet function of the nuclear capability and experience "math microscope," the magic examples : positioning plates.)

DWT的彩色水印嵌入算法，而且嵌入的水印附图像是彩色的。(DWT color watermark embedding algorithm, and the embedded watermark such as color drawings.)

图像匹配的实现，其中match.m：测试程序，sift.m :尺度不变特征变换（SIFT算法）的核心算法程序，appendimages.m: 该函数创建一个新的图像分别包含两个匹配的图像和他们之间的匹配对的连接直线，可以运行。 (The realization of image matching, which match.m: test program, sift.m: scale-invariant feature transform (SIFT algorithm) of the core algorithm, appendimages.m: This function creates a new image each consists of two images and matching match between them on the connection line, you can run.)

利用有限差分和MATLAB矩阵运算直接求解二维泊松方程(Directly solving the 2D Poisson equation using finite difference and MATLAB matrix operations)

很好的将lab空间中各颜色分量区分开，亲自使用过修改即可使用(It is very good to separate the color components in lab space.)

说明：  图像的Laplace金字塔分解与重构算法。(Laplacian pyramid decomposition and reconstruction of image. )

本程序是对24位图片进行灰度化，并进行去边缘的，二值化(This program is to 24 bits images of gray, and go to the edge, binary )
