针对动态场景下图像序列中运动目标检测问题, 首先采用基于分块投影匹配的全局运动参数估计方法, 然后利用估计得到的运动参数补偿背景的全局运动以稳定图像序列, 最后在稳定后的图像序列上采用背景减除法提取运动目标。实验表明, 分块投影匹配的运动目标检测能有效地提取动态背景下的运动目标。

Aiming at the moving target detection in image sequence for dynamic scene, block projection and matching were utilized for global motion estimation. Then, the background image was compensated by applying the estimated motion parameters so as to stabilize the image sequence. Finally, background subtraction was employed in the stabilized image sequence to extract moving targets. Experiment tests denote that the proposed moving target detection algorithm based on block projection and matching can efficiently extract moving targets in dynamic scene.
