{"url":"/dataset/ethz-shape","name":"ETHZ-Shape","full_name":"ETHZ-Shape","description_markdown":"The ETHZ Shape dataset contains images of five diverse shape-based classes, collected from Flickr and Google Images. The main challenges it offers are clutter, intra-class shape variability, and scale changes. The authors deliberately selected several images where the object comprises only a rather small portion of the image, and made an effort to include objects appearing at a wide range of scales. The objects are mostly unoccluded and are all taken from approximately the same viewpoint (the side).\n\nSource: [http://calvin-vision.net/datasets/ethz-shape-classes/](http://calvin-vision.net/datasets/ethz-shape-classes/)\nImage Source: [http://calvin-vision.net/datasets/ethz-shape-classes/](http://calvin-vision.net/datasets/ethz-shape-classes/)","description_withheld":null,"homepage":"http://calvin-vision.net/datasets/ethz-shape-classes/","introduced_date":"2008-01-01","introduced_date_note":null,"introduced_by":{"paper":null,"title":"Groups of Adjacent Contour Segments for Object Detection","first_author":null,"url":"https://doi.org/10.1109/TPAMI.2007.1144"},"license":null,"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[{"name":"Graph Learning","url":"/task/graph-learning","datasets_with_task":"/datasets/task/graph-learning"}],"languages":[],"variants":["ETHZ-Shape"],"data_loaders":[],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
