Connected Component Trees for Multivariate Image Processing and Applications in Astronomy
2010 20th International Conference on Pattern Recognition, 2010 In this paper, we investigate the possibilities offered by the extension of the connected component trees (cc-trees) to multivariate images. We propose a general framework for image processing using the cc-tree based on the lattice theory and we discuss the possible applications depending on the properties of the underlying ordered set.

Maximum-entropy image processing in gamma-ray astronomy [PDF]
Monthly Notices of the Royal Astronomical Society, 1979 Imaging γ-ray astronomy is a slowly evolving field because experiments are expensive, few and far between. For energies above 100 MeV the only satellite experiments to date with real imaging capabilities have been NASA’s SAS-2 and ESA’s COS-B. At lower energies (1-30 MeV) only balloon experiments have so far had imaging capabilities (e.g.

Quantum Radio Astronomy: Data Encodings and Quantum Image Processing
Astronomy and Computing, 2023 We explore applications of quantum computing for radio interferometry and astronomy using recent developments in quantum image processing. We evaluate the suitability of different quantum image representations using a toy quantum computing image reconstruction pipeline, and compare its performance to the classical computing counterpart. For identifying

Polyharmonic Daubechies type wavelets in image processing and astronomy, I [PDF]
Proceedings of the 11th International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing on International Conference on Computer Systems and Technologies, 2010 We introduce a new family of multivariate wavelets which are obtained by "polyharmonic subdivision". They generalize directly the original compactly supported Daubechies wavelets.
