Spatio-temporal interest points matching in video
Sarra Elabbessi, Mehrez Abdellaoui, Ali Douik · 2015
Despite the wide applications of matching descriptors, much work hasn't been done on it. In the current paper, we extended the use of the existing techniques in object detection in 2D images to video sequences by extracting the Spatio-temporal Interest points using spatio-temporal Harris detector. Features descriptors are computed on the pixels around these interest points. To match between descriptors, we build a KDTree using nearest neighbor search.
