histogram processing
In digital image processing, the histogram is used to represent a digital image. A graph is a plot by the number of pixels for each tonal value. Nowadays, image histogram is present in digital cameras. Photographers use them to see the distribution of tones captured.
In a graph, the horizontal axis is used to represent tonal variations whereas the vertical axis is used to represent the number of pixels in that particular pixel. Black and dark areas are represented on the left side of the horizontal axis, medium grey color is represented in the middle, and the vertical axis represents the size of the area.
