{"url":"/dataset/inria-horse","name":"INRIA-Horse","full_name":"INRIA-Horse","description_markdown":"The **INRIA-Horse** dataset consists of 170 horse images and 170 images without horses. All horses in all images are annotated with a bounding-box. The main challenges it offers are clutter, intra-class shape variability, and scale changes. The horses are mostly unoccluded, taken from approximately the side viewpoint, and face the same direction.\n\nSource: [Dynamical And-Or Graph Learning for Object Shape Modeling and Detection](https://arxiv.org/abs/1502.00741)\nImage Source: [http://calvin-vision.net/datasets/inria-horses/](http://calvin-vision.net/datasets/inria-horses/)","description_withheld":null,"homepage":"http://calvin-vision.net/datasets/inria-horses/","introduced_date":"2004-01-01","introduced_date_note":null,"introduced_by":{"paper":null,"title":"Scale-Invariant Shape Features for Recognition of Object Categories","first_author":null,"url":"http://doi.ieeecomputersociety.org/10.1109/CVPR.2004.218"},"license":null,"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[{"name":"Object Detection","url":"/task/object-detection","datasets_with_task":"/datasets/task/object-detection"},{"name":"Edge Detection","url":"/task/edge-detection","datasets_with_task":"/datasets/task/edge-detection"}],"languages":[],"variants":["INRIA-Horse"],"data_loaders":[],"num_papers_in_archive":2,"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."}
