Publication number: 20260094438Abstract: Systems and methods for summarizing a real-time event are disclosed herein. A system obtains a set of multimedia data feeds from image capturing devices, wherein the set of multimedia data feeds correspond to a real-time event. The system processes the obtained set of multimedia data feeds using model hyperparameters and sequences the processed set of multimedia data feeds in a predetermined order. The system also obtains one or more input prompts corresponding to the set of multimedia data feeds. The system generates an output representation of the real-time event by encoding the sequenced set of multimedia data feeds and the obtained one or more input prompts using a trained vision encoder model, wherein the generated output representation corresponds to a multi-resolution summary image of the real-time event at a time instance. The system also predicts one or more actions performed in the generated output representation using an action prediction model.Type: ApplicationFiled: October 1, 2024Publication date: April 2, 2026Applicant: ACCENTURE GLOBAL SOLUTONS LIMITEDInventors: Kamal MANNAR, Nita WANG, Hayley Skye DARUKHANAVALA, Lan GUAN, Elizabeth Ann KEATING
