Investigation on Combining 3D Convolution of Image Data and Optical Flow to Generate Temporal Action Proposals

11 Mar 2019Patrick SchlosserDavid MünchMichael Arens

In this paper, several variants of two-stream architectures for temporal action proposal generation in long, untrimmed videos are presented. Inspired by the recent advances in the field of human action recognition utilizing 3D convolutions in combination with two-stream networks and based on the Single-Stream Temporal Action Proposals (SST) architecture, four different two-stream architectures utilizing sequences of images on one stream and sequences of images of optical flow on the other stream are subsequently investigated...
