Unlike a traditional,\nlens-based camera where an image of the scene is directly recorded on the\nsensor pixels, each pixel in FlatCam records a linear combination of light from\nmultiple scene elements. A computational algorithm is then used to demultiplex\nthe recorded measurements and reconstruct an image of the scene. FlatCam is an\ninstance of a coded aperture imaging system; however, unlike the vast majority\nof related work, we place the coded mask extremely close to the image sensor\nthat can enable a thin system. We employ a separable mask to ensure that both\ncalibration and image reconstruction are scalable in terms of memory\nrequirements and computational complexity. We demonstrate the potential of the\nFlatCam design using two prototypes: one at visible wavelengths and one at\ninfrared wavelengths.","url_abs":"http://arxiv.org/abs/1509.00116v2","url_pdf":"http://arxiv.org/pdf/1509.00116v2.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":"flatcam-thin-bare-sensor-cameras-using-coded","repo_url":"https://github.com/ebezzam/lenslessclassification","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"pytorch","reach":{"status":"ok","spdx":"GPL-3.0"}},{"paper_slug":"flatcam-thin-bare-sensor-cameras-using-coded","repo_url":"https://github.com/tanjasper/ug2_2020_challenge2_devkit","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"image-reconstruction","task_name":"Image Reconstruction"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
