Image processing (Use programming )

Please consider the 4 pixel by 4 pixel image below:

202,118,148	237,141,151	250,172,164	239,166,169
122,41,36	175,53,18	228,118,43	233,134,60
70,49,62	86,35,49	150,39,43	169,58,56
151,132, 233	169,135,244	179,135,244	174,139,244

The table contains the RGB values of the sixteen pixels. All RGB values are in 8-bit, i.e. from 0 to 255.

With the assistance of programming (or Excel, or otherwise)

1. What would be the image be like if we choose to have uniform scalar quantization levels for each channel? Assume 2 bits for each R/G/B channel.
