OpenCV2:总结篇 imgproc(图像处理模块)

一.简介

二.常用的函数

void erode( InputArray src, OutputArray dst, InputArray kernel, Point anchor = Point(-1, -1), int iterations = 1, int borderType = BORDER_CONSTANT, const Scalar& borderValue = morphologyDefaultBorderValue() )

void dilate( InputArray src, OutputArray dst, InputArray kernel, Point anchor = Point(-1, -1), int iterations = 1, int borderType = BORDER_CONSTANT, const Scalar& borderValue = morphologyDefaultBorderValue() )

• src

　　　　输入图像为二值图像或灰度图像

void pyrDown( InputArray src, OutputArray dst, const Size& dstsize = Size(), int borderType = BORDER_DEFAULT )

void pyrUp( InputArray src, OutputArray dst, const Size& dstsize = Size(), int borderType = BORDER_DEFAULT )
