What is Graph Signal Denoising with FrGFT about?

The document presents a novel graph signal denoising method that utilizes total variation (TV) regularization and fractional graph Fourier transform (FrGFT) to enhance traditional denoising techniques. It discusses the mathematical framework for the proposed method, including the spectral-domain interpretation and the step-by-step procedure for denoising signals defined on graphs. The effectiveness of the method is demonstrated through experiments on temperature data from a sensor network, showing improveme
