4. (20 points) You have a 4-by-4 4-bit gray-scale image as shown to the right. (i) Compute the dynamic range of this image signal (2pt) (ii) Suppose you can now increase quantization levels of this image from the 4-bit to a higher value. Compute the number of gray-levels at the maximum quantization for human perception for this image. (beyond this quantization/intensity resolution there will be subsequent gray- levels that cannot be distinguished by human eyes (8pt) (iii) Show the result of histogram equalization on this image.
