分块特征匹配与局部差分结合的运动目标检测

摘要

针对摄像机在运动情况下运动目标检测问题的研究，提出了一种尺度不变特征变换图像分块特征匹配和局部差分算法相结合的运动目标检测方法。该方法不仅可以减少图像配准参数求解所需要的时间，弥补全局运动补偿对图像完整性的影响，并且可以在摄像机运动的情况下准确地检测出运动目标。实验证明了该方案的有效性。%To investigate the moving objects in the situation of camera moving,a method that combines the scale invariant feature transform block feature matching with the local differential algorithm is proposed. The method can not only reduce the cost time of image registration and compensate the global motion compensation,which effects on the integrity of the image,but also detect moving objects accurately. Finally,the ezperiment results can provide its effectiveness.
