Histogram equalization or Histogram linearization is represented by of the following equation:
A. sk =∑k j =1 nj/n k=0,1,2,……,L-1
B. sk =∑k j =0 nj/n k=0,1,2,……,L-1
C. sk =∑k j =0 n/nj k=0,1,2,……,L-1
D. sk =∑k j =n nj/n k=0,1,2,……,L-1
Answer:B
Histogram equalization or Histogram linearization is represented by of the following equation:
A. sk =∑k j =1 nj/n k=0,1,2,……,L-1 B. sk =∑k j =0 nj/n k=0,1,2,……,L-1 C. sk =∑k j =0 n/nj k=0,1,2,……,L-1 D. sk =∑k j =n nj/n k=0,1,2,……,L-1
Explanation: A plot of pk_ (rk) versus r_k is called a histogram .The transformation (mapping) given in sk =∑k j =0)k nj/n k=0,1,2,……,L-1 is called histogram equalization or histogram linearization.
