简介:
块匹配技术是一种图像处理和视频压缩中的关键技术,通过在空间或时间上寻找像素块的最佳匹配来实现如运动估计、去噪等功能。
Block Matching Algorithms for Motion Estimation are techniques used in video compression to estimate the motion of objects between frames. These algorithms search for similar blocks within a predetermined search area, aiming to find the best match that minimizes an error metric such as Mean Squared Error (MSE) or Sum of Absolute Differences (SAD). This process is fundamental in creating efficient and high-quality compressed video streams by representing motion with vector data rather than pixel-by-pixel differences.
