Claim One:
1. A device implemented method for providing local change detection in video comprising: determining one or more inlier keypoints and one or more outlier keypoints in a current frame of a video sequence based on one or more second inlier keypoints and one or more second outlier keypoints in one or more previous frames of the video sequence; warping the one or more second outlier keypoints in the one or more previous frames to a coordinate system of the current frame; applying a clustering technique to the outlier keypoints and the warped one or more second outlier keypoints in the coordinate system of the current frame to detect a cluster of the outlier keypoints and the warped one or more second outlier keypoints in the coordinate system of the current frame; generating an indicator of local region of interest change corresponding to the cluster and the current frame in response to the detected cluster; and initiating a process at the device in response to the local region of interest indicator.
