Splitting and Merging Image Channels













                • # split channels



                • b,g,r=cv2.split(input_image)



                • # show one of the channels (this is red - see that the sky is kind of

                   dark. try changing it to b)




                • plt.imshow(b, cmap='gray')



                • merged=cv2.merge([r,g,b])



                • # merge takes an array of single channel matrices



                • plt.imshow(merged)
