Optical coherence tomography (OCT) is a prevalent non-invasive imaging method
which provides high resolution volumetric visualization of retina. However, its
inherent defect, the speckle noise, can seriously deteriorate the tissue
visibility in OCT. Deep learning based approaches have been widely used for
image restoration, but most of these require a noise-free reference image for
supervision. In this study, we present a diffusion probabilistic model that is
fully unsupervised to learn from noise instead of signal. A diffusion process
is defined …
