7944 实验结果表明,基于多目标演化的模糊认知图学习算法可以有效降低结点数据误差与模型误差,能够更准确地得出概念结点间的因果关系。 The experimental results show that the fuzzy cognitive map based on multi-objective evolutionary learning algorithm can effectively reduce the node data error and model error, can more accurately the causal relationship between the concept nodes are obtained.
7945 张量积小波及其提升小波只强调图像的水平方向和垂直方向的边缘,造成其在应用于多聚焦图像融合时结果图像的空间分辨率不高; Tensor product small spread its ascension wavelet only emphasis on the edges of the image of the horizontal and vertical direction, cause its when applied to more focus on image fusion result image spatial resolution is not high;
7946 而二维四通道不可分小波对图像进行融合时虽有较高的空间分辨率,但由于对图像进行分解和重构时采用了卷积运算,使得融合方法的运算量增大。 And two-dimensional four-channel inseparable wavelet for image fusion, though there are high spatial resolution, but due to the image decomposition and reconstruction when used the convolution operation, the fusion method of computation.
7947 针对上述问题,把二维四通道不可分小波滤波器组进行提升分解,并提出了一种基于此提升分解方案的多聚焦图像融合方法。 Aiming at these problems, the two-dimensional four-channel inseparable group ascension decomposition wavelet filter, and proposes a kind of based on this decomposition scheme of the focus image fusion method.
7948 首先,对二维四通道不可分小波滤波器组的多相位矩阵进行提升分解,并利用所得提升方案对源图像进行分解; First, the two-dimensional four-channel inseparable wavelet filter group ascension of the multiple phase matrix decomposition, and by using the lifting scheme of source images are decomposed;
7949 其次,对分解后的低频子图像和高频子图像分别进行融合,得到融合金字塔; Secondly, after the decomposition of low frequency image and high frequency fusion with sub image respectively, get pyramid fusion;
7950 最后,做二维提升小波逆变换,得到融合后图像。 Finally, do the two-dimensional wavelet inverse transformation, ascension after fusion image.
7951 利用熵、平均梯度和清晰度等客观指标对融合结果进行评价。 Using entropy, average gradient and clarity objective index to evaluate the fusion results.
7952 实验结果显示,所建议提升小波融合方法比张量积小波和张量积提升小波融合方法及轮廓波融合方法有较高的清晰度,比提升之前的二维四通道不可分小波融合方法速度有了较大提升。 The experimental results show that the proposed improve wavelet fusion method than the tensor product wavelets and tensor product wavelet fusion method and contour wavelet fusion method have higher resolution, the two-dimensional four-channel than before ascension inseparable wavelet fusion method speed has been increased greatly.
7953 针对现有的主瓣航迹欺骗干扰技术进行航迹规划时仅考虑运动参数限制和单部干扰机为主的问题,通过参考具有普遍适用性的航迹关联准则,提出虚假航迹设定方法,推导干扰机运动参数和干扰信号调制参数。 In view of the existing main lobe track is deception jamming technology to track motion parameters is only considered when planning restrictions and single jammer is given priority to, through the reference of universal applicability of correlation criterion, false path set method is proposed, jammer is derived kinematic parameters and the disturbance signal modulation parameters.
