Estimating tremors from video is important for non-invasive\nmonitoring, analyzing and diagnosing patients suffering from motor-disorders\nsuch as Parkinson's disease. We consider two approaches for hand-tremor\nfrequency estimation: (a) a Lagrangian approach where we detect the hand at\nevery frame in the video, and estimate the tremor frequency along the\ntrajectory; and (b) an Eulerian approach where we first localize the hand, we\nsubsequently remove the large motion along the movement trajectory of the hand,\nand we use the video information over time encoded as intensity values or phase\ninformation to estimate the tremor frequency.\n  We estimate hand tremors on a new human tremor dataset, TIM-Tremor,\ncontaining static tasks as well as a multitude of more dynamic tasks, involving\nlarger motion of the hands. The dataset has 55 tremor patient recordings\ntogether with: associated ground truth accelerometer data from the most\naffected hand, RGB video data, and aligned depth data.","url_abs":"http://arxiv.org/abs/1809.03218v1","url_pdf":"http://arxiv.org/pdf/1809.03218v1.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":[],"tasks":[],"methods":[],"datasets_introduced":[{"slug":"tim-tremor","name":"TIM-Tremor","full_name":"Technology in Motion Tremor"}],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
