In the dark room we cannot observe the minute details. But if we turn on the light we can see the minute details also. Similarly in image if the image is very dark or taken in night we need to apply some technique to adjust the contrast of that image to see each and every detail or in simple word we need to turn on light digitally. There are many techniques to adjust the contrast of the image like contrast stretching, histogram equalization, etc. Here the technique used is Histogram Equalization
