Publication number: 20180025749Abstract: Described are various technologies that pertain to automatically generating looped videos or cinemagraphs by selecting objects to animate from an input video. In one implementation a group of semantically labeled objects from an input video is received. Candidate objects from the input video that can appear as a moving object in an output cinemagraph or looped video are identified. Candidate video loops are generated using the selected candidate objects. One or more of these candidate video loops are then selected to create a final cinemagraph. The selection of candidate video loops used to create the final cinemagraph can be made by a user or by a predictive model trained to evaluate the subjective attractiveness of the candidate video loops.Type: ApplicationFiled: September 14, 2016Publication date: January 25, 2018Inventors: Tae-Hyun Oh, Sing Bing Kang, Neel Suresh Joshi, Baoyuan Wang

Patent number: 9779774Abstract: A cinemagraph is generated that includes one or more video loops. A cinemagraph generator receives an input video, and semantically segments the frames to identify regions that correspond to semantic objects and the semantic object depicted in each identified region. Input time intervals are then computed for the pixels of the frames of the input video. An input time interval for a particular pixel includes a per-pixel loop period and a per-pixel start time of a loop at the particular pixel. In addition, the input time interval of a pixel is based, in part, on one or more semantic terms which keep pixels associated with the same semantic object in the same video loop. A cinemagraph is then created using the input time intervals computed for the pixels of the frames of the input video.Type: GrantFiled: September 14, 2016Date of Patent: October 3, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Sing Bing Kang, Neel Suresh Joshi, Hugues Hoppe, Tae-Hyun Oh, Baoyuan Wang
