Computer Vision is a branch of Information Technology and Artificial Intelligence that enables computers to acquire, process, analyze, and interpret visual information from digital images and videos. It attempts to replicate human vision by extracting meaningful information from visual data for decision-making and automation. The following concepts are fundamental to understanding computer vision. (i) Pixel and Image Resolution A pixel, short for "picture element," is the smallest unit of a digital image. Every digital image consists of thousands or millions of pixels arranged in a grid. Each pixel stores information about brightness and color, typically represented through RGB (Red, Green, and Blue) values or grayscale intensity. The quality and clarity of an image largely depend on the number of pixels it contains. Image resolution refers to the total number of pixels present in an image, commonly expressed as width × height, such as 1920 × 1080
