    "PaddleDetection has provide out-of-the-box tools in pedestrian and vehicle analysis, and it support multiple input format such as images/videos/multi-videos/online video streams. This make it popular in smart-city\\smart transportation and so on. It can be deployed easily with GPU server and TensorRT, which achieves real-time performace.\n",
