On a non-local spectrogram for denoising one-dimensional signals

13 Nov 2013Gonzalo GalianoJulián Velasco

In previous works, we investigated the use of local filters based on partial differential equations (PDE) to denoise one-dimensional signals through the image processing of time-frequency representations, such as the spectrogram. In this image denoising algorithms, the particularity of the image was hardly taken into account... (read more)
