How to convert LAB to RGB Python OpenCV

In this article, you’ll see how to convert LAB to RGB in OpenCV. I highly recommend you get the “Computer Vision: Models, Learning, and Inference Book” to learn Computer Vision. You need to just follow these steps:

Step 1: Install OpenCV

If OpenCV is not installed, then first install it using this code.

pip install opencv-python

Step 2: Import the OpenCV library

import cv2

Step 3: Read the LAB Image

Now read the LAB image from the location.

image = cv2.imread("C:\\AiHints\\lab_image.jpg")

Step 4: Convert into RGB

In this step, convert the image from Lab to RGB using cv2.cvtColor() function.

rgb_image = cv2.cvtColor(image, cv2.COLOR_LAB2RGB)

Step 5: Display Output

cv2.imshow("Lab Image", image)
cv2.imshow("RGB Image", rgb_image)

cv2.waitKey(0)
cv2.destroyAllWindows()

Output:
