The default format of RGB in OpenCV is BGR. So, you can get the intensity of your image using OpenCV like below: intensity_image = cv2.cvtColor(original_image, cv2.COLOR_BGR2HSV); intensity_image[:,:,2] is the value image of your original image. Hope this helps. Web12 de jun. de 2024 · Masking. Image masking is an image processing technique that is used to remove the background from which photographs those have fuzzy edges, transparent or hair portions. Now, we’ll create a mask that is in shape of a circular disc. First we’ll measure distance from center of the image to every border pixel values.
