{"url":"/task/local-color-enhancement","name":"Local Color Enhancement","slug":"local-color-enhancement","description_markdown":"Enhancement techniques for improving the contrast between lesion and background skin on dermatological macro-images are limited in the literature. To fill this gap, a modified sigmoid transform is applied in the HSV color space. The crossover point in the modified sigmoid transform that divides the macro-image into lesion and background is predicted using a modified EfficientNet regressor to exclude manual intervention and subjectivity.","categories":[{"name":"Computer Vision","url":"/area/computer-vision"}],"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","slug_source":"archive_url"},"counts":{"papers_tagged":5,"papers_with_code":3,"benchmarks":1,"benchmark_tables_in_archive":1,"benchmark_tables_shown":1,"benchmark_tables_withheld_as_spam":0,"benchmark_definition":"a leaderboard table with at least one row; benchmark_tables_shown also counts the zero-row tables; benchmark_tables_in_archive adds the tables withheld as spam","datasets":1,"subtasks":0,"parent_tasks":1},"benchmarks":[{"leaderboard":"/sota/local-color-enhancement-on-university-of","slug":"local-color-enhancement-on-university-of","dataset":"University of Waterloo skin cancer database","dataset_url":"/dataset/university-of-waterloo-skin-cancer-database","rows_in_archive":3,"metrics":["Dice (Average)"],"first_row_in_archive_order":{"model":"EMST","paper_title":"An EfficientNet-based modified sigmoid transform for enhancing dermatological macro-images of melanoma and nevi skin lesions","paper_url":"/paper/an-efficientnet-based-modified-sigmoid","paper_date":"2022-07-17","arxiv_id":null,"code_links":[{"title":"VipinBioLab/EMST","url":"https://github.com/VipinBioLab/EMST"}],"syntology":null}}],"datasets":[{"url":"/dataset/university-of-waterloo-skin-cancer-database","name":"University of Waterloo skin cancer database","full_name":"","num_papers_in_archive":8}],"subtasks":[],"parent_tasks":[{"url":"/task/image-enhancement","name":"Image Enhancement"}],"papers":{"order":"repositories listed in the archive (desc), then date (desc); the archive holds no stars","population":"papers tagged with this task that list at least one repository in the archive","shown":3,"of":3,"tagged_in_all":5,"items":[{"url":"/paper/an-efficientnet-based-modified-sigmoid","title":"An EfficientNet-based modified sigmoid transform for enhancing dermatological macro-images of melanoma and nevi skin lesions","date":"2022-07-17","arxiv_id":null,"repositories_listed":1,"syntology":null},{"url":"/paper/pixelrl-fully-convolutional-network-with","title":"PixelRL: Fully Convolutional Network with Reinforcement Learning for Image Processing","date":"2019-12-16","arxiv_id":"1912.07190","repositories_listed":1,"syntology":null},{"url":"/paper/fully-convolutional-network-with-multi-step","title":"Fully Convolutional Network with Multi-Step Reinforcement Learning for Image Processing","date":"2018-11-10","arxiv_id":"1811.04323","repositories_listed":1,"syntology":null}],"syntology_records":0,"syntology_note":"a paper without a record is not a recorded non-run: it may lack an arXiv id or simply be absent from the graph layer"},"description_links":{"kept":0,"unwrapped_to_text":0,"bare_urls_linked":0,"relative_images_dropped":0,"rule":"internal links are kept only when the target slug exists in the catalog"},"syntology":{"read_at":"2026-09-24T18:15:14+00:00","claim":"Per-sample execution status on synthesized fixtures ('ran N of M samples'); not a correctness claim and not a ranking signal.","status_vocabulary":{"ran_honours":"ran, honoured the contract we drafted","ran_violates":"ran, violated the contract we drafted","ran_draft_wrong":"ran; our contract draft was wrong, not the code","ran_fixture":"ran; our fixture could not drive it","ran":"ran on a synthesized input","unverified":"unverified (harvested, no recorded run)"}},"not_shown":{"libraries":"the archive has no per-task library table","trend_sparklines":"the Trend column of the benchmarks table was a rendered image; it is not in the archive","social_and_latest_sorts":"stars and social signals are not in the archive"}}
