摘要
现有的USB/CAN通信转换信号多尺度边缘重建算法存在着重建信号质量差、迭代收敛速率低的缺陷,提出USB/CAN通信转换信号多尺度边缘重建算法,以解决上述问题。采用稠密度聚类方法对USB/CAN通信转换信号进行增强处理,通过小波变换对信号多尺度边缘特征进行提取,以得到的信号多尺度边缘特征集合为依据,在多尺度下对多尺度边缘特征进行融合,采用反复投影算法对信号多尺度边缘进行重建,实现USB/CAN通信转换信号多尺度边缘的重建。实验结果显示,与现有重建算法相比较,所提算法极大地提升了重建信号质量与迭代收敛速率,充分说明所提算法具备更好的性能。
The existing multi-scale edge reconstruction algorithms of USB/CAN communication conversion signal have the defects of poor signal quality and low iterative convergence rate. The multiscale edge reconstruction algorithm of USB/CAN communication conversion signal is proposed to solve the above problems. Dense degree of clustering method is used to enhance the USB/CAN communication switching signal,the signal by wavelet transform multi-scale edge feature is extracted,in order to get the signal based on multi-scale edge character set,under the multi-scale fusion of multi-scale edge character of the signal multi-scale edge by projection algorithm repeatedly rebuilt,realization of USB/CAN communication conversion signal multi-scale edge reconstruction. Experimental results show that compared with the existing reconstruction algorithm,the proposed algorithm greatly improves the reconstruction signal quality and iterative convergence rate,which fully indicates that the proposed algorithm has better performance.
