Abstract

Although the image object detection technology developed quickly, the object detection in videos has special conditions such as motion blur, video defocus, part occlusion, rare posture, and needs to keep the target detection result consistent in time. It cannot apply image object detection models directly on videos. In this paper, we proposed the video object detection method based on the YOLO-v3 together with the FlowNet 2.0 optical flow extraction network to make full use of the information of the consistent video frames. The proposed Flow-guided Partial Warp method operates at the feature map level to make the detection result more accurate. In order to solve the motion blur influence of background, the optical flow compression by bilinear interpolation can minimize the influence. Meanwhile, the proposed method also uses the frame skipping to avoid the repeated use of convolutional neural networks in frames with little change, which reduces the consumption of computing resources and speeds up the running of the model. In addition, this paper also attempts to use the autonomous vehicles simulator as the input data of the video target detection algorithm. Finally, after testing in some typical scenarios, the detection results of most scenes are obviously improved after using optical flow guidance and aggregation feature maps.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Experimental results show that using depth information, optical flow information, and LiDAR point clouds in addition to conventional RGB data can improve the performance of one-stage based detection systems.

    “According to experimental results, it has been shown that the use of depth information [183, 184], optical flow information [185], and LiDAR point clouds [186] in addition to conventional RGB data can improve the performance of one-stage based detection systems.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
