ClassSR combines classification and SR in a unified framework. In particular, it first uses a Class-Module to classify the sub-images into different classes according to restoration difficulties, then applies an SR-Module to perform SR for different classes. The Class-Module is a conventional classification network, while the SR-Module is a network container that consists of the to-be-accelerated SR network and its simplified versions.","description_state":"present","introduced_year":null,"introduced_by":{"title":"ClassSR: A General Framework to Accelerate Super-Resolution Networks by Data Characteristic","paper":"/paper/classsr-a-general-framework-to-accelerate","first_author":"Xiangtao Kong","n_authors":4,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/classsr-a-general-framework-to-accelerate"},"source":{"url":"https://arxiv.org/abs/2103.04039v1","title":"ClassSR: A General Framework to Accelerate Super-Resolution Networks by Data Characteristic","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"Computer Vision","area_id":"computer-vision","collection":"Image Super-Resolution Models","url":"/methods/category/image-super-resolution-models","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":1,"papers_newest_first":[{"paper":"/paper/classsr-a-general-framework-to-accelerate","title":"ClassSR: A General Framework to Accelerate Super-Resolution Networks by Data Characteristic","date":"2021-03-06","arxiv_id":"2103.04039","n_code_links":3,"syntology":{"ran":7,"of":9,"unverified":2,"pointer_only":9}}],"papers_shown":1,"tasks":[{"task":"/task/2k","name":"2k","papers":1},{"task":null,"name":"8k","papers":1},{"task":"/task/classification-1","name":"Classification","papers":1},{"task":"/task/classification","name":"General Classification","papers":1},{"task":"/task/super-resolution","name":"Super-Resolution","papers":1}],"tasks_shown":5,"n_tasks":5,"usage_by_year":[{"year":"2021","papers":1}],"row_source":"methods_table","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/classsr"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
