[Vector Quantization] 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. By using K-means clustering, we aim to quantize the image into 4 levels of color.

With the assistance of programming (or Excel, or otherwise), compute a reasonable final set of quantization levels for the image. You can use whatever programming language you are familiar with.
