实现了遥感图像可以进行阈值分割和分水岭分割(Threshold segmentation, watershed segmentation)

说明：  基于灰度矩的亚像素边缘检测，零件边缘提取(Subpixel edge contour extraction)

一个很好类子来说明类模板的使用，可以比较明了类模板的使用方法，最好进行单步调试(use of class template )

说明：  抠图中最为经典和基本的算法贝叶斯抠图，在matlab下的实现，效果和速度都较为理想。(Bayessian Matting is the most basic and classic method in matting algorithm.We provide a implementation in matlab.)

说明：  sift算法实现的图像匹配程序，使用matlab编写的，多用于图像拼接，融合等领域。(The image matching program implemented by SIFT algorithm is written by MATLAB, and it is mostly used in image splicing, fusion and other fields.)

对一幅图片批量添加20个级别的噪声，支持添加高斯白噪声和椒盐噪声两种噪声。(Add a picture batch 20 levels of noise, two noise support the addition of white Gaussian noise and salt and pepper noise.)

说明：  基于DWT域的脆弱水印，上数字图像处理课的大作业(Fragile watermarking based on DWT, digital image processing course)

输入一组数据，xy值，用来拟合椭圆。只要改变输入数据，该代码就可以直接使用。另附上椭圆拟合算法。(Enter a set of data, xy values, used to fit ellipses. Just change input data, the code can be used directly. Attached on the ellipse fitting algorithm.)

采用haar小波实现二维图像的分解与重构（mallat算法）：(Two-dimensional image using haar wavelet decomposition and reconstruction (mallat algorithm):)

本程序实现了基于m-PCNN的医学图像融合算法，即多通道PCNN图像融合。(use for fusion)
