Incoherent digital holography
WebHolographic imaging may become severely degraded by a mixture of speckle and incoherent additive noise. Bayesian approaches reduce the incoherent noise, but prior information is needed on the noise statistics. With no prior knowledge, one-shot reduction of noise is a highly desirable goal, as the recording process is simplified and made faster. WebThe method is applied to generate edge-enhanced images in both CAI as well as Fresnel incoherent correlation holography methods. Next Article in Journal. Respiratory Inductive …
