摘要: In this paper we propose a robust method to suppress the noise components in digital holography (DH), called SPADEDH (SPArsity DEnoising of Digital Holograms), that does not consider any prior knowledge or estimation about statistics noise. full holographic process must mainly deal with two kinds The first one is an additive uncorrelated corrupts observed irradiance, other multiplicative phase speckle We both lensless and microscope configurations prove proposed algorithm works efficiently all considered cases suppressing aforementioned components. addition, for holograms recorded configuration, show improvement display test by using Spatial Light Modulator (SLM).
