Let me provide you with more details:\r\n\r\n1. **Dataset Overview**:\r\n   - The **PortraitMode-400 (PM-400)** dataset is the **first of its kind** and is dedicated to **portrait mode video recognition**.\r\n   - It was created to address the unique challenges associated with recognizing videos captured in portrait mode.\r\n   - Portrait mode videos are increasingly important due to the growing popularity of smartphones and social media applications.\r\n\r\n2. **Data Collection and Annotation**:\r\n   - The dataset consists of **76,000 videos** collected from **Douyin**, a popular short-video application.\r\n   - These videos were meticulously annotated with **400 fine-grained categories**.\r\n   - Rigorous quality assurance measures were implemented to ensure the accuracy of human annotations.\r\n\r\n3. **Research Insights and Impact**:\r\n   - The creators of the dataset conducted a comprehensive analysis to understand the impact of video format (portrait mode vs. landscape mode) on recognition accuracy.\r\n   - They also explored spatial bias arising from different video formats.\r\n   - Key aspects of portrait mode video recognition were investigated, including data augmentation, evaluation procedures, the importance of temporal information, and the role of audio modality.\r\n\r\n(1) [2312.13746] Video Recognition in Portrait Mode - arXiv.org. https://arxiv.org/abs/2312.13746.\r\n(2) Video Recognition in Portrait Mode | Papers With Code. https://paperswithcode.com/paper/video-recognition-in-portrait-mode.\r\n(3) Video Recognition in Portrait Mode - arXiv.org. https://arxiv.org/pdf/2312.13746.pdf.\r\n(4) undefined. https://doi.org/10.48550/arXiv.2312.13746.","description_withheld":null,"homepage":"https://github.com/bytedance/Portrait-Mode-Video","introduced_date":"2023-12-21","introduced_date_note":null,"introduced_by":{"paper":"/paper/video-recognition-in-portrait-mode","title":"Video Recognition in Portrait Mode","first_author":"Mingfei Han","url":null},"license":null,"modalities":[],"tasks":[],"languages":[],"variants":["PortraitMode-400"],"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":"2026-09-25T09:33:49+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."}
