直方图均衡化 --自编（由于选图不太好，效果不是很好） 代码如下（示例）： #-*- coding:utf-8 -*- import numpy as np import matplotlib.pyplot as plt import pandas as pd import cv2 originalImg = cv2.imread('121.jpg') # print(originalImag.shape) R , G , B = cv2.split(originalImg) # print(R.shap

灰度变换、图像反转、幂律变换、对比度变换 import cv2 import numpy as np OriginalImg = cv2.imread('cns.jpg') R ,B, G = cv2.split(OriginalImg) # print(R.shape) # print(G.shape) # print(B.shape) #灰度变换 NewImg = R*0.299 + G*0.587 + B*0.114 NewImg1=np.uint8(NewImg) print(NewImg1.
