Speckle attenuation in optical coherence tomography by curvelet shrinkage
We describe an algorithm based on shrinkage in the curvelet domain to attenuate speckles in optical coherence tomography (OCT) images. The algorithm exploits the curvelet transform’s sparse representation of edge discontinuities that are common in OCT images and its ability to map signals and noise...
