Such algorithms are effective because platelets approximate images in certain (piecewise) smoothness classes significantly more efficiently than sinusoids, wavelets, or wedgelets. Platelet representations are especially well-suited to the analysis of Poisson data, unlike most other multiscale image representations, and they can be rapidly computed. We present a fast, platelet-based maximum penalized likelihood algorithm that encompasses denoising, deblurring, and tomographic reconstruction and its applications to photon-limited imaging.engWaveletsPoissonmultiresolutiondenoisingtomographyImage Processing and Pattern analysisWavelet based Signal/Image ProcessingMultiscale MethodsMedical Imagining ApplicationsConference paperWaveletsPoissonmultiresolutiondenoisingtomographyhttp://dx.doi.org/10.1109/IEMBS.2002.1106257
