Weighted Anisotropic-Isotropic Total Variation for Poisson Denoising
Kevin Bui, Yifei Lou, Fredrick Park +1
Poisson noise commonly occurs in images captured by photon-limited imaging systems such as in astronomy and medicine. As the distribution of Poisson noise depends on the pixel inte…

Difference of Anisotropic and Isotropic TV for Segmentation under Blur and Poisson Noise
Kevin Bui, Yifei Lou, Fredrick Park +1
In this paper, we aim to segment an image degraded by blur and Poisson noise. We adopt a smoothing-and-thresholding (SaT) segmentation framework that finds a piecewise-smooth solut…
