Solving this\nproblem can be computationally intensive and usually leads to a quadratic or at\nleast superlinear complexity w.r.t. the number of pixels in the image. We\ninvestigate in this work the use of convolutional neural networks for image\nreconstruction in astronomy. With neural networks, the computationally\nintensive tasks is the training step, but the prediction step has a fixed\ncomplexity per pixel, i.e. a linear complexity. Numerical experiments show that\nour approach is both computationally efficient and competitive with other state\nof the art methods in addition to being interpretable.","url_abs":"http://arxiv.org/abs/1612.04526v2","url_pdf":"http://arxiv.org/pdf/1612.04526v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"astronomical-image-reconstruction-with","repo_url":"https://github.com/rflamary/AstroImageReconsCNN","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"tf","reach":null},{"paper_slug":"astronomical-image-reconstruction-with","repo_url":"https://github.com/mirapy-org/mirapy","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"tf","reach":null}],"tasks":[{"task_slug":"astronomy","task_name":"Astronomy"},{"task_slug":"image-reconstruction","task_name":"Image Reconstruction"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
