In the grayscale change experiment of image preprocessing, the gamma change function is defined as follows:
Xxxxxxxxxx
Def gamma_trans (img, gamma)
Gamma_list = [ np.power (x/255.0,gamma)*255.0 for x in range(256)]
Gamma_table = np.round ( np.array ( gamma_list )). astype (np.uint8)
Return cv2.LUT(img , gamma_table )
When the gamma value is 0.5, the bright part is stretched and the dark part is compressed.
