| 摘 要： | 提升目标检测模型的泛化能力是计算机视觉领域的研究热点和关键难点。本文提出了一种Multi-Patch方法和多帧增量式预测策略,提升了不同场景下交通视频目标检测的稳健性,有效解决了目标尺度多变导致的视频中目标召回率低的问题。根据视频分辨率和目标尺寸,基于Multi-Patch方法自动将视频帧分割成最佳输入尺寸,使用YOLO v4神经网络并关联连续帧的上下文信息,采用增量式预测策略降低视频目标检测的漏检率,提升不同场景下视频目标的检测置信度得分和召回率。采集不同拍摄条件下的交通视频,验证该方法的有效性。试验结果表明,本文提出的目标检测方法召回率在80%以上,置信度平均得分在0.84以上。

| Abstract: | Improving the generalization ability of object detection model is a research focus and key issue in the field of computer vision. This paper proposes a Multi-Patch method and a multi-frame incremental prediction strategy to improve the robustness of traffic video object detection in different scenarios, and effectively solve the problem of low object recall ratio in videos caused by variable object scales. According to the video resolution and object size, the video frame is automatically divided into the best input size based on the Multi-Patch method, the YOLO v4 neural network is used to correlate the context information of the continuous frame, and the incremental prediction strategy is used to reduce the missed detection rate of the video object detection, and to improve the detection confidence score and recall rate of video object in different scenarios. Collect traffic videos under different shooting conditions to verify the effectiveness of the algorithm. Experimental results show that the object detection method proposed in this paper has a recall rate of more than 80% and an average confidence score of more than 0.84. |
