Mask Images
Understand how to use masking techniques in OpenCV with Python. Learn to create blank images, design crescent-shaped masks using circles and rectangles, and apply these masks with bitwise operators to edit and highlight specific regions in images.

We can use the bitwise operators to mask images. Masking is another essential tool to edit images in OpenCV. In this lesson, we’ll follow the steps below.
First, we’ll create a blank image.
To create a blank image, we use the np.zeros() function of the OpenCV library.
blank = np.zeros(img.shape[:2], dtype='uint8')
