Figure 5. Memory visualization. Each example contains original frames, (a) mis-aligned memory and (b) motion-aided memory. Motion information is quite necessary for feature propagation. It helps MMNet align the feature when the objects move to a different position. - "Fast Object Detection in Compressed Video"

Most of the deep learning methods use CNNs to process each decoded frame in a video stream individually. In this paper, we propose a fast object detection model that incorporates light-weight motion-aided memory network (MMNet), which can be directly used for H.264 compressed video. 2018-11-27 · To our best knowledge, the MMNet is the first work that explores a convolutional detector on a compressed video and a motion-based memory in order to achieve significant speedup. Our model is evaluated on the large-scale ImageNet VID dataset, and the results show that it is about 3x times faster than single image detector R-FCN and 10x times faster than high performance detectors like FGFA and MANet. 2018-11-27 · To our best knowledge, the MMNet is the first work that investigates a deep convolutional detector on compressed videos. Our method is evaluated on the large-scale ImageNet VID dataset, and the results show that it is 3x times faster than single image detector R-FCN and 10x times faster than high-performance detector MANet at a minor accuracy loss.

Most of these deep learning models rely on RGB images to localize and identify objects in the image.

For each video frame I t, an image stack consisting of I t and a reference video frame I r e f is passed into a 1 × 1 convolutional layer to compute a motion probability map. Object detection in still images has drawn a lot of attention over past few years, and with the advent of Deep Learning impressive performances have been achieved with numerous industrial applications. Most of these deep learning models rely on RGB images to localize and identify objects in the image.
