CV_Canny

+

Finds edges in image using Canny algorithm

+ + +

Calling Sequence

+ 
edges = CV_Canny(srcimg,threhold1,threshold2,aperture_size,L2gradient)
+ +

Parameters

+
srcimg : +

single-channel 8-bit input image.

+
threshold1 : +

first threshold for the hysteresis procedure.

+
threshold2 : +

second threshold for the hysteresis procedure.

+
aperture_size : +

aperture size for the Sobel() operator.

+
L2gradient : +

a flag, indicating whether a more accurate

+ +

Description

+

This function can be used for finding edes in single channel 8 bit +image. 'aperture_size' and 'L2gradient' are optionals. By default, +aperture_size is 3 and L2gradient is false.

+

For L2gradient: L_2 norm =sqrt{(dI/dx)^2 + (dI/dy)^2} should be used to calculate the image gradient magnitude (L2gradient=1 ), or whether the default L_1 norm =|dI/dx|+|dI/dy| is enough (L2gradient=0).

+

This is curretly dummy function. It provides no functionality but is required +for providing support for generating C code for OpenCV

+

+ +

Examples

+ 
img = CV_LoadImage('~/test.jpg',0)
+dst = CV_CvtColor(img,"CV_RGB2GRAY");
+edge = CV_Canny(dst,50,100,3,0);
