一种基于图像特征块匹配的电子稳像算法

提出一种基于特征模块匹配的图像稳定算法。该算法自适应地搜索图像特征模块进行后续稳像操作。在稳像过程中，提出一种图像特征匹配的快速算法，匹配得到局部运动矢量，然后对匹配结果进行一致性检验，最后采用可变窗口宽度的均值滤波法对图像序列运动轨迹滤波。试验表明，该算法有效地稳定了图像序列，并且满足实时性要求。

Electronic Image Stabilization Method Based on Feature Block Matching

A method basic on feature block matching,which could search the feature block image aptively. And then a fast matching method is presented,to get the local motion vector and then verify the matching results. Finally, a mothod based on alterable windows filter to smooth the motion vector is introduce. Experimental results show that this algorithm not only smooth out the image sequences but also satisfy the demand of the real -time system.
