Arithmetic Operations on Images - OpenCV
Bitwise Operations. This includes the bitwise AND, OR, NOT, and XOR operations. They will be highly useful while extracting any part of the image (as we will see in coming chapters), defining and working with non-rectangular ROI's, and etc. Below we will see an example of how to change a particular region of an image.

DSA Notes: Understanding Algorithm Analysis and Basic Concepts
Bitwise operators perform operations on the binary representation of numbers. Common operators include: * AND (&): Sets a bit if both corresponding bits are 1. * OR (|): Sets a bit if at least one of the corresponding bits is 1. ... Mastering Python: Key Concepts from Handwritten Notes.

Extract horizontal and vertical lines by using morphological operations
Two of the most basic morphological operations are dilation and erosion. Dilation adds pixels to the boundaries of the object in an image, while erosion does exactly the opposite. The amount of pixels added or removed, respectively depends on the size and shape of the structuring element used to process the image. In general the rules followed ...

Bitwise AND operator: Sets each bit to 1 if both bits are 1. Here's the basic syntax for using cv.bitwise_and() in Python: result = cv.bitwise_and(Image 1, Image 2, mask) In this syntax: • Image 1 and Image 2 are the input images or arrays on which you want to perform the bitwise AND operation.

Morphological Transformations - OpenCV
Morphological transformations are some simple operations based on the image shape. It is normally performed on binary images. It needs two inputs, one is our original image, second one is called structuring element or kernel which decides the nature of operation. Two basic morphological operators are Erosion and Dilation.

Hit-or-Miss theory - OpenCV
These operators apply one or more structuring elements to an input image to obtain the output image. The two basic morphological operations are the erosion and the dilation . The combination of these two operations generate advanced morphological transformations such as opening , closing , or top-hat transform.
