automatic-human-video-extraction's Introduction

Automatic-human-video-extraction (自动人体视频提取)

  1. 按镜头切割后得到的视频片段
  2. 按运动信息过滤静态/低于阈值(低于10)的视频
  3. 按人体信息以及文字所占图像面积(高于2.5%)过滤视频
    1. 一个视频片段只取3~7帧进行进检测识别
    2. Yolov8模型检测是否包含人体,并过滤含有多人场景以及单人所占区域面积小于20%的视频
    3. Dwpose模型检测人体是否完整出现,按预测姿态点数量分为[0,1,2,3,4] 5个等级
      1. 0 表示上半身都没有
      2. 1 表示上半身有,下半身没有
      3. 2 表示上半身有,下半身有,但膝盖没有
      4. 3 表示上半身有,下半身有,膝盖有,但脚踝没有
      5. 4 表示上半身有,下半身有,膝盖有,脚踝有
    4. 人体分割模型与文本检测模型都同时执行,过滤人体分割图与文本框重叠区域占比大于10%的视频
  4. 按音视同步信息是否同步进行过滤,检测唇动和语音相匹配的帧序列

需要下载的权重

  1. download dwpose/yolox_l.onnx and dw-ll_ucoco_384.onnx, put them into video_process/pose_detection_model/weights dir.
  2. download yolo_weights/yolov8x.pt and put it into video_process/yolo_weights dir.
