Currently, I am doing histogram equalization on a 16 bit image, would the range change from [0, 65536] after the process?
import numpy as np
hist, bins = np.histogram(img.flatten(), 65536, [0, 65536]) # Collect 16 bits histogram (65536 = 2^16)
Does histogram equalization change the pixel intensity range? (16-bit)
