However, there is a clear lack of representative datasets\nto investigate the problem further. To address this shortcoming, this paper\npresents a novel image dataset called CubiCasa5K, a large-scale floorplan image\ndataset containing 5000 samples annotated into over 80 floorplan object\ncategories. The dataset annotations are performed in a dense and versatile\nmanner by using polygons for separating the different objects. Diverging from\nthe classical approaches based on strong heuristics and low-level pixel\noperations, we present a method relying on an improved multi-task convolutional\nneural network. By releasing the novel dataset and our implementations, this\nstudy significantly boosts the research on automatic floorplan image analysis\nas it provides a richer set of tools for investigating the problem in a more\ncomprehensive manner.","url_abs":"http://arxiv.org/abs/1904.01920v1","url_pdf":"http://arxiv.org/pdf/1904.01920v1.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":"cubicasa5k-a-dataset-and-an-improved-multi","repo_url":"https://github.com/CubiCasa/CubiCasa5k","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"pytorch","reach":{"status":"ok","spdx":"NOASSERTION"}}],"tasks":[],"methods":[],"datasets_introduced":[{"slug":"cubicasa5k","name":"CubiCasa5K","full_name":null}],"methods_introduced":[],"results":[],"syntology":{"syntology_url":"https://syntology.ai/paper/1904.01920","atlas_url":"https://app.syntology.ai/?focus=1904.01920","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
