Then the reflectance component is\nscaled up to improve the image details in bright areas. The illumination\ncomponent is scaled up and down to generate several illumination images that\ncorrespond to certain camera exposure values different from the original. The\nvirtual multi-exposure illuminations are blended into an enhanced illumination,\nwhere we also propose a method to generate appropriate weight maps for the tone\nfusion. Finally, an enhanced image is obtained by multiplying the equalized\nillumination and enhanced reflectance. Experiments show that the proposed\nalgorithm produces visually pleasing output and also yields comparable\nobjective results to the conventional enhancement methods, while requiring\nmodest computational loads.","url_abs":"http://arxiv.org/abs/1708.00636v1","url_pdf":"http://arxiv.org/pdf/1708.00636v1.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":"generation-of-high-dynamic-range-illumination","repo_url":"https://github.com/JasonBournePark/EnhanceHDR","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"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}
