Document Type and Number:
Japanese Patent JP5455101
Kind Code:
B2
Abstract:
A system of this invention is a video processing system for detecting a change of a capturing target based on a video whose capturing range changes. This video processing system includes a capturing unit that captures the video whose capturing range changes, a feature extractor that extracts a frame feature of each frame from the captured video, a feature storage that stores, for each frame, the frame feature extracted by the feature extractor, a frame searcher that searches for a frame, a frame feature of which is stored in the feature storage, having a capturing range matching that of the newly captured frame by comparing a frame feature of a newly captured frame with the frame features stored in the feature storage, and a change detector that detects a change of the capturing target based on a difference between the frame feature of the newly captured frame and the frame feature of the frame found by the frame searcher. With this arrangement, it is possible to detect a change of a capturing target even if the capturing range of a capturing apparatus changes every moment.
