摘　　要：传统的运动目标检测方法不能精确检测目标发生仿射形变,为此提出一种动态模板匹配改进算法。该算法首先利用改进后的瞬时差分算法对序列图像中的运动物体进行检测和定位,提高检测与识别的实时性;其次,采用仿射不变矩作为提取目标时的不变特征,从而克服不能有效检测与识别时发生仿射形变目标的缺点。实验仿真结果表明,该算法优于传统的动态模板匹配算法。The traditional dynamic template matching algorithm has disadvantage when it detects the affine deformation target. For that reason, a novel improved dynamic template matching algorithm is proposed in this paper. Firstly, the improved temporal difference algorithm is used to detect the moving targets for improving real-time quality of the algorithm. Secondly, affine invariant moment is used as the invariable characteristic for overcoming the shortcoming that it can not recognize the affine deformation target. Experimental results indicate that, compared with traditional dynamic template matching algorithm, our method has better detection performance.
