cv2.calcHist (images, channels, mask, histSize, ranges [, hist [, accumulate]]) images : it is the source image of type uint8 or float32 represented as “ [img]”. hist: Input histogram that can be dense or sparse. backProject: Destination back projection array that is a single-channel array of the same size and depth as images[0] . ranges: Array of arrays of the histogram bin boundaries in each dimension. See calcHist. scale: Optional scale factor for the output back projection.

channels : it is the index of channel for which we calculate histogram. Python: cv2.calcHist(images, channels, mask, histSize, ranges [, hist [, accumulate]]) → hist¶ C: void cvCalcHist(IplImage** image, CvHistogram* hist, int accumulate=0, const CvArr* mask=NULL )¶ Python: cv.CalcHist(image, hist, accumulate=0, mask=None) → None¶ The function cv::calcHist calculates the histogram of one or more arrays.

Namely, we use the normed parameter to normalize the histogram and a couple of different options  This histogram is a graph showing the number of pixels in an image at each to the discrete character of the intensity values, the histogram is not entirely flat. It improves the contrast and brightness of an image, in order to stretch out the intensity range.

For 2D set(h, ' import cv2 import numpy as np from matplotlib import pyplot as plt img = cv2. imread('wiki.jpg',0) hist,bins = np.histogram(img.flatten(),256,[0,256]) cdf  The method flatten() converts any array to a one-dimensional array with values taken row-wise.

Let’s familiarize with the function and its parameters : cv2.calcHist(images, channels, mask, histSize, ranges[, hist[, accumulate]]) images : it is the source image of type uint8 or float32. it should be given in square brackets, ie, “[img]”. To remedy this, a simple call to cv2.cvtColor is made on Line 27 to convert the image from BGR to RGB. Computing the color histogram is handled on Line 32.
