An image uses 512 x 512 picture elements. Each of the picture elements can take any of the 8 distinguishable intensity levels. The maximum entropy in the above image will be
Answer: Option
Explanation:
Picture elements (pixel) = 512 x 512 = 262144
Information per picture element N = log2 M
M = 2N
8 = 2N
N = 3
Information for 262144 pixels = 262144 x 3 = 786432 bits
Entropy is same as average information per message.
