Publication number: 20250054224Abstract: The present disclosure relates to a method and apparatus for representing dynamic neural radiance fields from unsynchronized videos. A method of acquiring a video at an arbitrary viewpoint based on a dynamic neural radiance fields model according to an embodiment of the present disclosure may comprise: inputting one or more videos acquired from one or more views for one scene into the dynamic neural radiance fields model; inputting a time embedding for the one or more videos into the dynamic neural radiance fields model; and rendering the video at the arbitrary viewpoint based on color information and density information output by the dynamic neural radiance fields model. Herein, time synchronization related to the time embedding may be performed by applying an individual time offset learned for each view, for the one or more views.Type: ApplicationFiled: August 9, 2024Publication date: February 13, 2025Applicants: Electronics and Telecommunications Research Institute, UIF (University Industry Foundation), Yonsei UniversityInventors: Ha Hyun LEE, Gun Bang, Soo Woong Kim, Ji Hoon Do, Seong Jun Bae, Jin Ho Lee, Jung Won Kang, Young Jung Uh, Seo Ha Kim, Jung Min Bae, Young Sik Yun
