    • Denoising using adaptive thresholding and higher order statistics 

      Kozaitis, Samuel P.; Young, Tim (2009-03-19)
      We showed that a hard threshold for wavelet denoising based on higher order statistics is comparable to a second order soft threshold. The hard threshold can be made adaptive by using a third order statistic as an estimate ...
    • Thresholding for higher-order statistical denoising 

      Kozaitis, Samuel P.; Young, Tim (2008-04-03)
      Hard thresholding seems to work well for denoising signals using higher-order statistics. We statistically examined the best values for hard thresholding and related this to the fraction of wavelet coefficients set to zero ...
