2020“马栏山”杯国际音视频算法大赛图像赛道demo
- OpenCV python >= 3.4.2
- OpenCV-Contrib-Python >= 3.4.2
安装依赖
pip install -r requirements.txt- baseline.py baseline脚本
- baseline.mp4 示例视频文件
- target_points.txt 跟踪目标点，格式为： frame_index x1,y1 x2,y2 x3,y3 x4,y4 （frame_index=0）
- groundtruth.txt gt 文件
- results.txt 结果输出
- preview.py 预览输出结果脚本
- evaluate.py 评估单个结果脚本
python baseline.py baseline.mp4 target_points.txt results.txt
将得到 results.txt 且格式如下:
格式如下：
frame_index x1,y1 x2,y2 x3,y3 x4,y4
frame_index 从0帧到最后一帧。
x{n},y{n} 代表四个点位，x与y之间,分隔；点位与点位以及与frame_index之间以单个空格分隔
示例内容如下:
