遠端偵測人的移動與其動作辨識,包括:

  • 前景與背景顏色相近時,前景影像獲取
  • 陰影偵測與干擾消除
  • 隨前景人體移動或靜止而調整之適應性背景模型建構
  • 搭配上述人體動作辨識系統,進行人體追蹤與動作辨識
  • 偵測範圍:人體高度 10 pixels 以上

  • We can extract the foreground image reliably when the foreground color is similar to the background color.
  • We utilize the HSV color space to build the background model.
  • It is also helpful to remove shadow.
  • The background model is also adaptive to the change of scene containing newly moving or stationary person.
  • The module can be integrated into a robust Human Activity Recognition System.
