Project description
imhist
This model calculates the histogram of a given matrix fast.
Usage
import cv2
import numpy as np
from imhist import imhist, imcdf
import matplotlib.pyplot as plt
img = cv2.imread('assets/Plane.jpg')
hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
v = hsv[:, :, 2].copy()
v_hist = imhist(v)
plt.figure(num=1)
plt.plot(np.arange(256), v_hist, 'b', label='Histogram')
plt.ylabel('Number of Occurrences')
plt.xlabel('Brightness')
plt.grid(which="both")
plt.legend()
plt.show()
Output
This is a sample image:
