多尺度的光谱图像分割，有对应的论文和matlab及c++代码(Multiscale spectral image segmentation, there are papers and the corresponding matlab and c++ code)

图像数字水印中所涉及到的代码以及具体的文字的详细说明(The code involved in the image digital watermarking)

本文叙述了用数字图象处理技术实现天文图象目标的参数测量,重叠图象的分离、原以及星和银河的识别(This paper describes the use of digital image processing technology to achieve the objectives of astronomical images measured parameters, the separation of overlapping images, the original as well as the identification of stars and the Galaxy)

1.打开左右两张影像2.Harris算法提取同名点3.显示提取同名点（若要进行下一步匹配则不建议显示，这里只是用于查看是否提取出）4.相关系数匹配（只在找出的同名点内匹配）5.LSM最小二乘匹配（先进行粗匹配，再精匹配）(1 Open the left and right images 2.Harris algorithm to extract two tie points 3 shows the extraction of corresponding points (not recommended to proceed to the next match show, here is used to see if extracted) 4. Correlation coefficient matching (just looking match within a point of the same name) 5.LSM least squares matching (rough first match, then fine match))

可以用来计算MTF值，用matlab编写的，数据文件需要为Excel格式。(MTF can be used to calculate the value, using matlab prepared.)

HOG（方向梯度直方图）图像特征提取，以lena图像作为示例(HOG (Histogram of Oriented Gradients) image feature extraction, image as an example to lena)

图像中的对极几何问题，是一个了解和学习外极线约束方法的不错代码(Image epipolar geometry problems, is a knowledge and learning outside the epipolar constraint method of good code)

基于纹理分析的图像分割，matlab开发，用entropyfilt，stdfilt等(Image segmentation based on texture analysis, matlab development, with entropyfilt, stdfilt etc.)

简单图像压缩处理，正交变化，图像压缩灰度变化(Simple Image Compression Processing, Orthogonal Change, Gray Level Change of Image Compression)

这时高斯模糊的源码，对做图像盲复原的同学可以参考(Then Gaussian blur of the source, to make the image blind restoration of the students can refer to the)
