{"url":"/dataset/freiburg-across-seasons","name":"Freiburg Across Seasons","full_name":"Freiburg Across Seasons","description_markdown":"**Freiburg Across Seasons** captures long-term perceptual changes across a span of 3 years. Image sequences were recorded with a forward facing bumblebee stereo camera mounted on a car. During summer, the camera was mounted outside the car where as during winters the camera was inside the car. The image sequences are recorded at relatively low frame rates of 1Hz and 4Hz. All the images have a resolution of 1024 × 768 (width×height) and are JPEG compressed. In total, there are ground truth matchings for 8,133 images for localization based on GPS position.\n\nSource: [http://aisdatasets.informatik.uni-freiburg.de/freiburg_across_seasons/](http://aisdatasets.informatik.uni-freiburg.de/freiburg_across_seasons/)\nImage Source: [http://aisdatasets.informatik.uni-freiburg.de/freiburg_across_seasons/](http://aisdatasets.informatik.uni-freiburg.de/freiburg_across_seasons/)","description_withheld":null,"homepage":"http://aisdatasets.informatik.uni-freiburg.de/freiburg_across_seasons/","introduced_date":null,"introduced_date_note":null,"introduced_by":null,"license":null,"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[],"languages":[],"variants":["Freiburg Across Seasons"],"data_loaders":[],"num_papers_in_archive":0,"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":"2026-09-25T09:33:49+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."}
