Web– Option 1: Write a program to perform vector quantization on a gray scale image using 4x4 pixels as a vector. You should design your codebook using all the blocks in the image as training data, using the generalized Lloyd algorithm. Then quantize the image using your codebook. You can choose the codebook size, say, L=128 or 256.

WebIn this technique, we begin by designing a vector quantizer with a single output point; in other words, a codebook of size one, or a one-level vector quantizer.
