Abstract
A method for detecting objects in a video comprising: selecting an initial image frame m from the video, wherein the initial image frame m is preceded by a previous image frame m-p and followed by a subsequent image frame m+n; creating a first difference image by subtracting the subsequent image frame m+n from the initial image frame m; creating a second difference image by subtracting the initial image frame m from the previous image frame m−p; combining the first and second difference images to create a resulting image; concatenating the resulting image and the initial image frame m to create a concatenated input; and feeding the concatenated input into an object detection network configured to leverage motion-cue side information contained in the resulting image and the initial image frame m to facilitate rapid detection of moving objects in the video.
