摘要
在图像处理的实际应用中 ,正交性能保持能量 ,而对称性使信号在边界易于处理 ,双正交小波同时拥有这两种性质。本文提出一种在复杂背景下的运动目标的提取方法 ,充分利用此特性 ,并设计具体的双正交小波基 ,达到最佳的滤波和检测效果。通过实验证明 ,该方法对于弱小目标的提取具有较好的效果 。
In the fact application of the image procession, orthogonal capability can keep energy and symmetry capability is easier to process in the brim of the signal The double orthogonal wavelet holds both capabilities.A method of moving object pick-up under complex background is presented using the feature in this paper, and design idiographic the base of the Double orthogonal wavelet, in order to attain the optimal filter and inspection.Experiment, results show that the method is efficient to be used to the puniness object extracting, distill precede to traditional the way of brim inspection.
