| 摘 要： | 实现了一种基于块匹配法（Block Matching Algorithm）的电子稳像系统。系统使用TI公司的TMS320DM642专用图像处理芯片,稳像算法采用求和绝对误差（SAD,the Sum of Absolute Difference）作为块匹配的匹配准则来估算原始视频图像的运动矢量,SAD准则便于硬件实现。系统利用运动矢量对图像进行运动补偿后得到稳定的视频图像输出。

| Abstract: | This paper provides an electronic image stabilization system based on block matching algorithm.The system uses the specialized image-processing chip TMS320DM642 made by TI company,the stabilization algorithm uses the sum of absolute difference as the block matching algorithm criterion to estimate the motion vector of original video,SAD criterion is implemented easily in hardware.The system uses motion vector to make the motion compensation of the original video,then outputs the stabilized video. |
