Consider an 4 X 4 digital image A3, with 3-bit/pixel ( 0 – 7 gray scale levels and bin width =1). The numeric value per each pixel of image A.
  • (a) Suppose that image A3 is uniformly quantized with 2-bit accuracy to generate new image A2. Compute the numeric values of image B per each pixel.
  • (b) Repeat (a) but with 1-bit accuracy to generate new image A1, and compute the numeric values/pixels.
  • (c) Find the memory capacity in bits for the images A1, A2 and A3.
Hint: The table below illustrated the quantization process of 8-bit and 4-bit respectively.

Hint: divide A3 by a power of 2.
