1. 图像均衡化

wiki上的说明

OpenCV的[Histograms]

equ = cv2.equalizeHist(image)
res = np.hstack((image,equ))#两个图片并列拼接在一起,方便和原图对比
plt.imshow(res,cmap='bone')
clahe = cv2.createCLAHE(clipLimit=3.0, tileGridSize=(64,64))
cl1 = clahe.apply(image)
res = np.hstack((image,cl1))
fig = plt.figure(figsize=(10,20))
plt.imshow(res,cmap='bone')
img2 = cdf[img]
res = np.hstack((img,equ)) #stacking images side-by-side
