open cv 邊緣化 用Canny作邊緣化處理

cvCanny,



void cvCanny( const CvArr* image, CvArr* edges, double threshold1,

double threshold2, int aperture_size=3 )

image

單通道輸入圖像.

edges

單通道存儲邊緣的輸出圖像

threshold1

第一個閾值

threshold2

第二個閾值

aperture_size

Sobel 運算元內核大小 (見 cvSobel). -open cv for marginalized marginalized deal with the Canny cvCanny, void cvCanny (const CvArr* image, CvArr* edges, double threshold1, double threshold2, int aperture_size = 3)　image single input image. edges stored in the edge of the output channel Image threshold1 first threshold threshold2 second operand threshold aperture_size Sobel kernel size (see cvSobel).
