The histogram of a digital image with gray levels in the range [0, L-1] is represented by a discrete function:
A. h(r_k)=n_k
B. h(r_k )=n/n_k
C. p(r_k )=n_k
D. h(r_k )=n_k/n
Answer:A
The histogram of a digital image with gray levels in the range [0, L-1] is represented by a discrete function:
A. h(r_k)=n_k B. h(r_k )=n/n_k C. p(r_k )=n_k D. h(r_k )=n_k/n
Explanation: The histogram of a digital image with gray levels in the range [0, L-1] is a discrete function h(rk )=nk, where rk is the kth gray level and nkis the number of pixels in the image having gray level rk.
