1 Introduction Figure 1: An overview of the proposed Fast YOLO framework for object detection in video. 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.
But applications need to verify whether it meets their accuracy requirement. Comparison SSD MobileNet, YOLOv2, YOLO9000 and Faster R-CNN. Here is a video

Therefore, this paper proposes a fast object detection method in the compressed domain for High Efficiency Video Coding. Evaluation shows promising results for optimal object sizes. I. INTRODUCTION Advances in digital video capturing allow cameras to cap- #13 best model for Video Object Detection on ImageNet VID (MAP metric) 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.

Indexing deals with the automatic extraction of information with the objective of automatically describing and organizing the content. Thinking of a video stream, different types of information can be considered semantically important. Since we can assume that the most relevant one is linked to the presence of moving foreground objects, their number, their shape, and their appearance can

Further, key frame features are also aggregated based on optical flow. The propagated deep features are then integrated with the directly extracted features for object detection.

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.
