function edges = CV_Canny(srcimg,threhold1,threshold2,aperture_size,L2gradient)
//Finds edges in image using Canny algorithm
//
// Calling Sequence
// edges = CV_Canny(srcimg,threhold1,threshold2,aperture_size,L2gradient)
//
// Parameters
<<<<<<< HEAD
// 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);
