Abstract
Techniques related to detecting local change in video are discussed. Such techniques may include determining inlier and outlier keypoints for a current frame of a video sequence based on inlier keypoints from previous frames, detecting a region of local change based on outlier keypoints of the current and previous frames, and providing an indicator of local change based on the detected region of local change.
