说明: 在MTLAB环境运行main_msbcsspl.m。该程序的功能是实现图像的稀疏分解并重建图像,采用压缩感知理论,利用小波分析,在小波域分块观测,可以用很少的观测值就能重建原图像。程序包中已经整合了小波包和测试图像,没有多余文件,程序经过亲测并修改,能在MATLAB中直接运行得到很好的结果,速度非常快!(Run main_msbcsspl.m in the MTLAB environment. The function of the program is to decompose and reconstruct the image sparsely. Using compressed sensing theory and wavelet analysis, the original image can be reconstructed with very few observations. Wavelet package and test image have been integrated in the package. There are no redundant files. After testing and modifying the program, it can run directly in MATLAB and get good results. The speed is very fast.)

能够生成各种用于结构光的条纹,可供选择与使用(It is possible to generate various stripes for structural light)
从起始点和终止点同时进行RRT搜索,有效加快了搜索速度(RRT search at the same time from the starting point and the ending point effectively accelerates the search speed.)
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.)
