2 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.
