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
//	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);
