We validate\nour seven techniques on standard SR benchmarks (i.e. Set5, Set14, B100) and\nmethods (i.e. A+, SRCNN, ANR, Zeyde, Yang) and achieve substantial\nimprovements.The techniques are widely applicable and require no changes or\nonly minor adjustments of the SR methods. Moreover, our Improved A+ (IA) method\nsets new state-of-the-art results outperforming A+ by up to 0.9dB on average\nPSNR whilst maintaining a low time complexity.","url_abs":"http://arxiv.org/abs/1511.02228v1","url_pdf":"http://arxiv.org/pdf/1511.02228v1.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":[],"tasks":[{"task_slug":"image-super-resolution","task_name":"Image Super-Resolution"},{"task_slug":"super-resolution","task_name":"Super-Resolution"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/image-super-resolution-on-bsd100-4x-upscaling","task":"Image Super-Resolution","dataset":"BSD100 - 4x upscaling","model":"IA","rank_in_archive_order":51,"of":71,"metrics":{"PSNR":"27.16"},"uses_additional_data":false},{"leaderboard":"/sota/image-super-resolution-on-set14-4x-upscaling","task":"Image Super-Resolution","dataset":"Set14 - 4x upscaling","model":"IA","rank_in_archive_order":83,"of":104,"metrics":{"PSNR":"27.88"},"uses_additional_data":false}],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1511.02228","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
