It optimizes both\nthe JPEG global quantization tables and the DCT coefficient values in each JPEG\nblock using a closed-loop optimizer. Guetzli uses Butteraugli, our perceptual\ndistance metric, as the source of feedback in its optimization process. We\nreach a 29-45% reduction in data size for a given perceptual distance,\naccording to Butteraugli, in comparison to other compressors we tried.\nGuetzli's computation is currently extremely slow, which limits its\napplicability to compressing static content and serving as a proof- of-concept\nthat we can achieve significant reductions in size by combining advanced\npsychovisual models with lossy compression techniques.","url_abs":"http://arxiv.org/abs/1703.04421v1","url_pdf":"http://arxiv.org/pdf/1703.04421v1.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":"guetzli-perceptually-guided-jpeg-encoder","repo_url":"https://github.com/VenciFreeman/Compress","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"perceptual-distance","task_name":"Perceptual Distance"},{"task_slug":"quantization","task_name":"Quantization"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1703.04421","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
