Block Matching Algorithms

Block matching algorithms are techniques used in image and video processing to find similar areas within images. They work by dividing an image into small blocks or patches and then searching for the most similar matching block within a reference region, often in a previous frame or the same image. This process helps in tasks like motion detection, video compression, and image restoration. Essentially, the algorithm compares blocks to track how parts of the image move or change over time, allowing for efficient encoding or analysis of visual data.
