详解详解python中中GPU版本的版本的opencv常用方法介绍常用方法介绍
主要介绍了详解python中GPU版本的opencv常用方法介绍，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一
起学习学习吧
引言
本篇是以python的视角介绍相关的函数还有自我使用中的一些问题，本想在这篇之前总结一下opencv编译的全过程，但遇到了太多坑，暂时不太想回看做过的笔记，所以这里主要总结python下GPU版本
的opencv。
主要函数说明
threshold()：二值化，但要指定设定阈值
blendLinear()：两幅图片的线形混合
calcHist()
createBoxFilter ()：创建一个规范化的2D框过滤器
canny边缘检测
createGaussianFilter()：创建一个Gaussian过滤器
createLaplacianFilter()：创建一个Laplacian过滤器
createLinearFilter()：创建一个线形过滤器
createMorphologyFilter()：形态学运算滤波器；腐蚀、开、关等操作
createSolbelFilter()：创建一个solbel过滤器
createHougnCirclesDetector()：创建一个霍夫原检测器
createMedianFilter()：创建一个中值滤波过滤器
createTemplateMatching()：模板匹配
cvtColor()：颜色空间转换
dft()：执行浮点矩阵的正向或逆离散傅里叶变换
drawColorDisp()：颜色差异图像
equalizeHist()：将灰度图像的直方图均衡化
findMinMax()
findMinMaxLoc()
flip()：翻转二维矩阵
merge()：用几个单通道矩阵构成一个多通道矩阵
split()：将多通道矩阵分离成多个单通道矩阵
getCudaEnabledDeviceCount()：获取可用的gpu数目
getDevice()：返回由cuda::setDevice或默认初始化的当前设备索引
printCudaDeviceInfo()
resetDevice()：显示地销毁和清理与当前进程中当前设备相关的所有资源
setDevice()：设置一个device并为当前线程初始化它；如果省略次函数的调用，则在第一次CUDA使用时初始化默认设备
remap()：对图像应用一般的几个变换
resize()：调整一个图像大小
rotate()：在原点(0,0)周围旋转一个图像，然后移动它
sum()：返回矩阵元素的和
上述是在cv2.cuda下总结出来的一些可以使用的方法，因为底层是C++，并且python主要调用的是cv2.so文件，如果我们想要看到一个对象到底有什么样的作用还有一系列的使用方式，我们可以利用
python的魔法方法__dir__ 与help查看：
$ dir(cv2.cuda)
