Python OPENCV uses lab space to change the spring scene to fall

A period of time before the implementation of the Reinhard color migration algorithm, it is very interesting, and then made some changes in the code, there are some discoveries, the lab channel of a channel value changed to about 127, you can change the green to yellow, and the other color changes are very small, So you can change the scene of the spring to fall, here is the core code:

# -*-coding:utf-8-*- Import  = cv2.imread (' test. jpg'= cv2.cvtcolor (image,cv2. Color_bgr2lab) image[:,:,1] = 127= cv2.cvtcolor (image,cv2. COLOR_LAB2BGR) cv2.imwrite ('test.jpg', image)

The principle of implementation is very simple, as said above, but the effect is very good, paste a few results diagram:
