i need convert RGB image to YCbCr colour space, but have some colour shift problems, i used all formulas and got the same result. Formula in python cbcr[0] = int(0.299*rgb[0] + 0.587*rgb[1] + 0.114*rgb[2]) #Y cbcr[1] = int(-0.1687*rgb[0] - 0.3313*rgb[1] + 0.5*rgb[2]...
def imread_uint(path, n_channels=3): # input: path # output: HxWx3(RGB or GGG), or HxWx1 (G) if n_channels == 1: img = cv2.imread(path, 0) # cv2.IMREAD_GRAYSCALE img = np.expand_dims(img, axis=2) # HxWx1 elif n_channels == 3: img = cv2.imread(path, cv2.IMREAD_U...

Well, the point of all this is that, we really do not need to keep all the information that is now represented in these colour frames (Cb and Cr) and thus these are usually sub-sampled (like in JPEG compression). The formulae for converting from RGB to YCbCr are given below. Y = ...

Also, if you'd like to convert color space from RGB color space to other color space, the conversion formula depends on your correspond color space. Refer to the SMPTE standard or other required standard to find the conversion formula, if you'd like to know it. Best regards, Expand ...
Color spaceBecause of the powerful data processing ability of FPGA, the fast interpolation algorithm is used for Bayer format data which comes from CMOS sensor MT9M011 to convert to RGB image format. In the RGB color space to YCbCr space conversion stage, using color space conversion formula,...
