Abstract[English]
Systems and methods are described for performing a computer vision task on a sequence of frames. A first frame and a second frame are obtained, corresponding to a first timestep and a second timestep, respectively, in a sequence of frames. A differential image is computed between the first frame and the second frame. A predicted output is generated by forward propagating the differential image through a neural network that is trained to perform a computer vision task.[French]
L'invention concerne des systèmes et des procédés pour effectuer une tâche de vision par ordinateur sur une séquence d'images. Une première image et une seconde image sont obtenues, correspondant à un premier pas de temps et à un second pas de temps, respectivement, dans une séquence d'images. Une image différentielle est calculée entre la première image et la seconde image. Une sortie prédite est générée par propagation vers l'avant de l'image différentielle à travers un réseau de neurones qui est entraîné pour effectuer une tâche de vision par ordinateur.
