It draws a predicted bounding box distribution on an empty canvas for an attack model input. The canvas is initially set to an image of 300$\\times$300 pixels in size, where every pixel has a value of zero and the boxes drawn on the canvas have the same center as the predicted boxes and the same intensity as the prediction scores.","description_state":"present","introduced_year":null,"introduced_by":{"title":"Membership Inference Attacks Against Object Detection Models","paper":"/paper/membership-inference-attacks-against-object","first_author":"Yeachan Park","n_authors":2,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/membership-inference-attacks-against-object"},"source":{"url":"https://arxiv.org/abs/2001.04011v2","title":"Membership Inference Attacks Against Object Detection Models","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"General","area_id":"general","collection":"Inference Attack","url":"/methods/category/inference-attack","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":1,"papers_newest_first":[{"paper":"/paper/membership-inference-attacks-against-object","title":"Membership Inference Attacks Against Object Detection Models","date":"2020-01-12","arxiv_id":"2001.04011","n_code_links":1,"syntology":null}],"papers_shown":1,"tasks":[{"task":"/task/inference-attack","name":"Inference Attack","papers":1},{"task":"/task/membership-inference-attack","name":"Membership Inference Attack","papers":1},{"task":"/task/object","name":"Object","papers":1},{"task":"/task/object-detection","name":"Object Detection","papers":1},{"task":"/task/object-detection-1","name":"object-detection","papers":1}],"tasks_shown":5,"n_tasks":5,"usage_by_year":[{"year":"2020","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/canvas-method"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
