Histogram generation in c++
WebbThe hist () function will use an array of numbers to create a histogram, the array is sent into the function as an argument. For simplicity we use NumPy to randomly generate an array with 250 values, where the values will concentrate around 170, and the … WebbHistogram of an image is the graphical representation of the distribution of intensities of pixels. It provides an estimate of where pixel values are concentrated and whether there are unusual deviations. e.g. - Consider the following image. Say, all pixel values have a depth of 2 bits and are unsigned.

In Fig.1, we have a sample 5*5 image with pixel diversities from 0 to 4. In the first step for generating the histogram, we create the Histogram Table, by counting the number of each pixel intensities.
