Algorithms for\nsimultaneous computation of a fundamental matrix or a homography with unknown\ntime shift between images are developed. Our methods use minimal correspondence\nsets (eight for fundamental matrix and four and a half for homography) and\ntherefore are suitable for robust estimation using RANSAC. Furthermore, we\npresent an iterative algorithm that extends the applicability on sequences\nwhich are significantly unsynchronized, finding the correct time shift up to\nseveral seconds. We evaluated the methods on synthetic and wide range of real\nworld datasets and the results show a broad applicability to the problem of\ncamera synchronization.","url_abs":"http://arxiv.org/abs/1704.06843v1","url_pdf":"http://arxiv.org/pdf/1704.06843v1.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":[{"paper_slug":"on-the-two-view-geometry-of-unsynchronized","repo_url":"https://github.com/CenekAlbl/TwoViewUnsynch","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":{"status":"unanswered"}},{"paper_slug":"on-the-two-view-geometry-of-unsynchronized","repo_url":"https://github.com/impermanD/TwoViewUnsynch","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":{"status":"unanswered"}}],"tasks":[{"task_slug":"two","task_name":"Vocal Bursts Valence Prediction"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":"https://syntology.ai/paper/1704.06843","atlas_url":"https://app.syntology.ai/?focus=1704.06843","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
