摘要 依据主曲线的思想,重点对主曲线算法在信号去噪上的应用进行了研究。首先介绍了K主曲线的理论和实际算法,论述了原始算法的局限性,提出了对原始主曲线的改进算法,并和原始算法在处理能力上进行了性能比较,最后将改进算法进行去噪实验。实验数据表明改进的K主曲线算法在一定信噪比限制下去噪性能优良,并且对噪声种类影响不敏感。 According to the principal curves theory, the denoise technology is investigated by the principal curves algorithm. First, the paper introduces the theory and algorithm of K principal curves. Then several improvements are proposed to improve the limitations of the original algorithm. And the performances of both algorithms are compared. Finally, the improved algorithm is applied to a denoise experiment. Experiment results indicate that the performance of denoise is excellent under certain signal-to-noise ratio. And it is not sensitive to noise varieties.
