Bitwise operations

There are some operations that can be performed at bit level using bitwise operators, which can be used to manipulate the values for comparison and calculations. These bitwise operations are simple, and are quick to calculate. This means that they are a useful tool when working on images.

Bitwise operations include AND, OR, NOT, and XOR.

• Bitwise AND: bitwise_and = cv2.bitwise_and(img_1, img_2)
• Bitwise OR: bitwise_xor = cv2.bitwise_xor(img_1, img_2)
• Bitwise XOR: bitwise_xor = cv2.bitwise_xor(img_1, img_2)
• Bitwise NOT: bitwise_not_1 = cv2.bitwise_not(img_1)

In order to explain how these operations work, look at the output of the bitwise_operations.py script in the following screenshot:
