Supervised and Unsupervised Subband Adaptive Denoising Frameworks with Polynomial Threshold Function
Unlike inflexible structure of soft and hard threshold function, a unified linear matrix form with flexible structure for threshold function is proposed. Based on the unified linear flexible structure threshold function, both supervised and unsupervised subband adaptive denoising frameworks are esta...
