图像拼接算法中尺度不变特征转换（sift）源码。经过本人测试修改完全可用，对matlab还不怎么熟练的新手有很大帮助。(Image mosaic algorithm scale invariant feature transform (sift) source. After I test change is totally available, not on how skilled novice matlab great help.)

说明：  基于matlab的钢筋计数方法，有ui界面(MATLAB-based steel bar counting method with UI interface)

此文档中的代码可以计算5种图像的质量参数，分别是：图像灰度均值、图像方差、图像平均梯度、熵和峰值信噪比及均方误差。(The code in this document can be calculated five kinds of image quality parameters, namely: the image gray value, image variance, average gradient image, entropy and peak signal to noise ratio and mean square error.)

说明：  计算两个离散变量x和y的联合熵z = H（x，y）。 输入：x，y：两个相同长度的整数向量输出：z：联合熵 可以使用，有利于学习目的(Compute joint entropy z=H(x,y) of two discrete variables x and y. Input: of x, y: two integer vector of the same length Output: z: joint entropy good for learning purposes)

ZIGZAG程序，实现对图像矩阵ZIGZAG顺序读取。通常作为函数调用。还有就是霍夫曼编码的程序，得到图像霍夫曼的编码(ZIGZAG procedures ZIGZAG image matrix to achieve the order read. Usually as a function call. There is the Huffman code procedure, the image encoding Hoffman)

很全很全的基于压缩感知的图像重构算法啊，很适合用初学者的，本人就很受益( recovery algorithm)

物理光学法+物理绕射计算远场RCS的程序代码，c++程序(Physical optics+ physicaldiffraction computing far-field RCS program code, c++ program)

用matlab实现的对数极坐标转换图像配准算法，实验证明效果不错(Using matlab realize logarithmic polar coordinate conversion image registration algorithm, experiments show good results)

说明：  用delphi编程实现图像的颜色拾取，这是一个很好的图像处理程序(Delphi programming with the color of the image pick-up, this is a very good image processing program)
