Wavelets, Ridgelets, and Curvelets for Poisson Noise Removal [PDF]
IEEE Transactions on Image Processing, 2008 In order to denoise Poisson count data, we introduce a variance stabilizing transform (VST) applied on a filtered discrete Poisson process, yielding a near Gaussian process with asymptotic constant variance. This new transform, which can be deemed as an extension of the Anscombe transform to filtered data, is simple, fast, and efficient in (very) low ...

3-D Discrete Analytical Ridgelet Transform [PDF]
IEEE Transactions on Image Processing, 2006 In this paper, we propose an implementation of the 3-D Ridgelet transform: the 3-D discrete analytical Ridgelet transform (3-D DART). This transform uses the Fourier strategy for the computation of the associated 3-D discrete Radon transform. The innovative step is the definition of a discrete 3-D transform with the discrete analytical geometry theory ...

Papers in Palaeontology, Volume 11, Issue 3, May/June 2025.Abstract Fossilized food items found in or passed through the digestive tract of an animal (bromalites) offer a window into the dietary habits and ecological role of the producer taxon. Bromalites have been documented from several small to mid‐sized parvipelvian ichthyosaurian species from the Lower Jurassic, but are seldom documented for the largest ...

Active Seismic Exploration of Planetary Subsurfaces via Compressive Sensing
Earth and Space Science, Volume 12, Issue 3, March 2025.Abstract Geophysical measurements, such as seismic experiments, are a key target for scientific activities on planetary surfaces. Dense spatial sampling of such measurements is often desirable, and acquisition is traditionally performed at regular intervals.
