Title
(EN) LOCAL CHANGE DETECTION IN VIDEO
(FR) DÉTECTION DE CHANGEMENT LOCAL DANS UNE VIDÉO
Abstract
(EN)
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.
(FR)
L'invention concerne des techniques liées à la détection d'un changement local dans une vidéo. Ces techniques peuvent comprendre les étapes consistant à déterminer des points-clés conformes et non conformes pour une trame actuelle d'une séquence vidéo d'après des points-clés conformes de trames précédentes, à détecter une région de changement local d'après des points-clés non conformes de la trame actuelle et des précédentes, et à fournir un indicateur de changement local d'après la région de changement local détectée.
