Model Infos

• source: https://www.tensorflow.org/lite/models/pose_estimation/overview
• file name: posenet_mobilenet_v1_100_257x257_multi_kpt_stripped.tflite
• file size: 13.3 MB
• input: [1, 257, 257, 3]
  • rgb color image
  • need normalized input 0.0~1.0
• outputs: 4 output - postprocess in iOS
  • outputs[0]: [1, 9, 9, 17]
    • 17 heatmaps (because 17 keypoints output)
  • outputs[1]: [1, 9, 9, 34]
    • 17 * 2 offsets (because col and row offsets output) → as input size
  • outputs[2]: [1, 9, 9, 32] - ??
  • outputs[3]: [1, 9, 9, 32] - ??
