说明：  对高光谱图像进行目标检测，首先滤波处理然后降维，利用输出能量最小原则用于探测亚像元的小目标。(In target detection of hyperspectral images, first filter processing and then dimensionality reduction are used to detect sub-pixel small targets by using the principle of minimum output energy.)

最大类间方差法是由日本学者大津(Nobuyuki Otsu)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2部分。背景和目标之间的类间方差越大,说明构成图像的2部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2部分差别变小。(The largest between-class variance method was proposed by the Japanese scholar Nobuyuki Otsu in 1979. It is an adaptive threshold determination method, also known as the Otsu method, or OTSU for short. It is based on the grayscale characteristics of the image and divides the image into two parts: the background and the target. The larger the variance between the background and the target, the greater the difference between the two parts that make up the image. When the part of the target is wrongly divided into backgrounds or part of the background is mis-divided into goals, the difference between the two parts will be smaller.)

三维重建程序，包括数据和代码，用的是SFM的方法，课程设计(Three-dimensional reconstruction program, including data and code, using SFM method, course design)

说明：  给出一些离散的点，根据最小二乘法求出拟合的直线。(If there are some discrete points, you can get a line based on least square method.)

压缩传感重构算法：稀疏基采用离散余弦变换的omp重构算法(Compressed sensing reconstruction algorithm: sparse basis using the discrete cosine transform reconstruction algorithm omp)

matlab 实现对图像离散像素的曲面拟合，和差值比较，可实现细分等算法(the program is used to image in high resolution among image process system)

能完成基本二维条形码的识别，包含gui界面编程，可对较为清晰的拍摄二维条形码图像进行识别(To complete the basic two-dimensional bar code recognition, including the gui interface can be programmed to take on a more clear two-dimensional bar code image to identify)

3D图形编程，让你形象的看到一座山峰，同时也能举一反三运用到其他画图的方面。(3D graphics programming, so you see the image of a mountain, but also can be applied to other aspects of replicability drawing.)

自己总结的JPG,GIF,BMP,PNG,WBMP图片文件格式文档(Own summary of JPG, GIF, BMP, PNG, WBMP image file format documents)

一个自己好玩的程序，主要是用三角面片构成一个球，三角面片的面积相同但形状不同(a fun own procedures, it is mainly used triangular facets pose a ball, and the triangular facets of the same size but different shapes)
