Abstract

Systems and methods detect moving objects in image data of a monocular video stream using a trained CNN-based object-feature extractor (2) and a trained CNN-based motion-feature extractor (4) operating in parallel branches on the input video stream, with the feature sets produced by the features extractors being concatenated and supplied to a detection head (6). The object-feature extractor (2) is trained to generate output comprising class-agnostic features. The motion-feature extractor (4) is trained to generate output including first (backward) motion-features (M_t―1) relating to motion between a subject image frame and the previous image frame and second (forward) motion-features (M_t+1) relating to motion between the subject image frame and the next image frame, based on respective backward and forward motion cost volumes.
