| 摘 要： | 针对传统纹理分割方法的不足,从分形布朗运动的平均Holder数出发,提取人造目标与自然场景的相对距离,根据相对距离区分物体和背景,通过不同分辨率下的小波Holder数的计算,进行直线拟合．利用拟合后直线的斜率及线性度等参数可进行目标的检测．实验表明,与用单纯的分形特征参数相比,所提出的方法是一种快速、有效的人造目标识别方法．

| Abstract: | A novel method of target recognition based on multi resolution analysis and Holder constant is proposed. With the description of the average Holder constant of fractional Brownian motion and analyzing the different distance of 3D surface between the target and complex background, the wavelet Holder constants are calculated in a serial of images. The target is recognized by the detection of the linearity error and some parameters. The experiments show that this method is suitable for identifying specific targets and is good in noise immunity. |
