OpenCV 데이터 타입 변환입 변환

import cv2
import numpy as np

source = cv2.imread("data/images/sample.jpg")

scalingFactor = 1/255.0

# Convert unsigned int 8bit to float

source = np.float32(source)
source = source*scalingFactor
print(source)

# Convert back to unsigned int(8bit)
source = source*(1.0/scalingFactor)
source = np.uint8(source)
print(source)
