DOI: 10.1107/s1600577522002739
Abstract: Streaks and Poissonian noise in tomography data are attenuated using a new two-stage multiscale volumetric filtering framework where the degradations are modeled as correlated noise. The procedure is fully automatic, offers improved feature preservation, and… read more here.

DOI: 10.1109/lsp.2021.3096160
Abstract: Limited by the number of available photons collected by a pixel and the stability of the imaging system, images captured under poor illumination conditions are often degraded by heavy shot noise and low contrast. In… read more here.

DOI: 10.1109/tit.2020.2979978
Abstract: This paper considers estimation of a random variable in Poisson noise with signal scaling coefficient and dark current as explicit parameters of the noise model. Specifically, the paper focuses on properties of the conditional mean… read more here.

DOI: 10.3390/math11102260
Abstract: Multi-modal image fusion can provide more image information, which improves the image quality for subsequent image processing tasks. Because the images acquired using photon counting devices always suffer from Poisson noise, this paper proposes a… read more here.
