Research on improved K principal curves denoise performance
Zhong Zi-fa · Systems engineering and electronics · 2009
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.
