Multiplication Aimed at Median Nonlinear Laplase Pattern Plate

针对低信噪比图像序列中空间拉普拉斯模板对准相乘法对方向和噪声都很敏感的问题 ,将中值滤波和非线性拉普拉斯算子引入 ,得到了一种在低信噪比条件下有效地提取运动目标的方法——中值非线性拉普拉斯模板对准相乘法。理论分析和实验结果表明 ,该方法对方向和噪声都不敏感 。

In consideration of the hardness of extracting motion objects in the image series of low SNR, median filtering and nonlinear Laplase operator are introduced in calculation, and a method - median nonlinear Laplase pattern plate aimed at product is obtained for effectively extracting motion objects under a lower SNR condiction. The result shows that the method has a strong ability of noise abatement and boundary extraction.
