"- Using the TotalVariation class, from CIL. This solves the TV denoising problem (using the FGP algorithm) in CPU. The default warmstart=True, means that the TV denoising problem is initialised each time with the solution of the previous run of the TV denoising problem. This means we can use as few as 10 iterations of FGP and increases computation speed. \n",
