Block Matching

Block Matching is a technique used in image and video processing to track motion or enhance images. It works by dividing an image into small sections or "blocks" and comparing these blocks to those in adjacent frames. By finding where each block has moved or changed, it helps determine how objects in a scene are moving over time. This method is crucial in applications like video compression, where it reduces data by only recording changes, and in motion analysis, where understanding movement is essential for various technologies, including video surveillance and sports analysis.
