Command	Description
`ASSOC`	Displays or modifies file extension associations.
`ATTRIB`	Displays or changes file attributes.

	cmake_minimum_required(VERSION 2.8)
	project(sample-testcv)

	#这里使用 NO_DEFAULT_PATH 可以避免自动识别到安装的路径
	find_package( OpenCV REQUIRED PATHS "/home/guohw/projects/opencv-all/build" NO_DEFAULT_PATH)

	include_directories( ${OpenCV_INCLUDE_DIRS} )
	message("opencv dir: " ${OpenCV_INCLUDE_DIRS})

	add_executable(test_stereo_quasi test_QuasiDenseStereo.cpp )

	import numpy as np
	import matplotlib.pyplot as plt

	#%%
	def generateData(n = 30):
	# similar to peaks() function in MATLAB
	g = np.linspace(-2.0, 2.0, n)
	X, Y = np.meshgrid(g, g)
	X, Y = X.reshape(-1,1), Y.reshape(-1,1)
	#a, b, c, d , e = -5, -5, 1, 1, 10

	# 简单获取文件加下的文件的绝对路径
	files_depth=($path_images/$folder_name/Depth/*)

	# 路径分割字符串
	## 例子中分割符号 /; 得到的ss 是个数组 ss[0] ss[-1]进行索引
	IFS="/"; read -ra ss <<< "$file_depth"; unset IFS

	## 选取字符串子串
	${result_name:0:-4}
