some notes

  • Android ndk camera is used for best efficiency
  • Crash may happen on very old devices for lacking HAL3 camera interface
  • All models are manually modified to accept dynamic input shape
  • Most small models run slower on GPU than on CPU, this is common
  • FPS may be lower in dark environment because of longer camera exposure time
