Convert RGB to gray / other color spaces

Parameters:	src – input image: 8-bit unsigned, 16-bit unsigned ( CV_16UC.. ), or single-precision floating-point. dst – output image of the same size and depth as src. code – color space conversion code (see the description below). dstCn – number of channels in the destination image; if the parameter is 0, the number of the channels is derived automatically from src and code .

This function converts one image from one colorspace to another.The default color format in openCV is RGB.But is is actually BGR(byte reversed).so in an 24 bit color image the first 8 bits are blue components,2nd byte is green and third one is red.
