USING MATLAB

Use the command: imread to read the JPG image peppers.jpg and plot the Red, Green and Blue channel separately. Notice how the image array uses data type uint8 for each RGB pixel i.e. each value is stored as1-byte (8-bit) unsigned integer that goes from 0 to 255. Quantize the image to be represented with only 4 bitsi.e. each RGB pixel should now be an integer going from 0 to 15. In other words, replicate result of Fig 3.15(c)on slide 20 of the Introduction chapter. Show your results.
