Action Recognition with Dynamic Image Networks

Bilen, Hakan; Fernando, Basura; Gavves, Efstratios; Vedaldi, Andrea


We introduce the concept of dynamic image, a novel compact representation of videos useful for video analysis, particularly in combination with convolutional neural networks (CNNs). A dynamic image encodes temporal data such as RGB or optical flow videos by using the concept of 'rank pooling'. The idea is to learn a ranking machine that captures the temporal evolution of the data and to use the parameters of the latter as a representation. We call the resulting representation dynamic image...[Show more]
