Question

In a dark image, the components of histogram are concentrated on which side of the grey scale?

(a) High

(b) Medium

(c) Low

(d) Evenly distributed

This question was posed to me in examination.

My question is from Histogram Processing in division Intensity Transformations and Spatial Filtering of Digital Image Processing

Answer 1

Correct answer is (c) Low

To explain I would say: We know that in the dark image, the components of histogram are concentrated mostly on the low i.e., dark side of the grey scale. Similarly, the components of histogram of the bright image are biased towards the high side of the grey scale.
