Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. An apparatus for analyzing a video shot, comprising:
at least one program and memory in which the program is recorded; and
a processor for executing the at least one program,
wherein the at least one program includes
a frame extraction unit for extracting at least one frame from a video shot;
a shot composition and camera position recognition unit for predicting a shot composition and a camera position for the extracted at least one frame based on a previously trained shot composition recognition model;
a place and time information extraction unit for predicting a shot location and a shot time for the extracted at least one frame based on a previously trained shot location recognition model and a previously trained shot time recognition model; and
an information combination unit for combining pieces of information, which are respectively predicted for the extracted at least one frame, for each video shot and tagging the video shot with the combined pieces of information,
wherein the place and time information extraction unit predicts the shot location and the shot time for the extracted at least one frame by inputting at least one of a shot composition of the extracted at least one frame, which is predicted based on the previously trained shot composition recognition model, a color distribution of the extracted at least one frame, and a key frame, to the shot location recognition model and the shot time recognition model.
