Denoising and deconvolving CT images of unknown origin: comparing linear Wiener-deconvolution with deep convolutional neural network Noise2Inverse
Low-dose CT scans are very fast, but they feature strong pixel noise which, in turn, invites for efficient denoising the same way that strong image blur invites for sharpening the images.Wiener-deconvolution serves as a starting point, combining these two operations in a linear Fourier filter.It may apply in 2D or 3D and requires merely estimates o
