To-Do list for Human library

Work in Progress

Exploring

• Switch to custom tfjs for main human ESM bundle
• Optical Flow: https://docs.opencv.org/3.3.1/db/d7f/tutorial_js_lucas_kanade.html
• Histogram Equalization: Regular, Adaptive, Contrast Limited
• TFLite Models: https://js.tensorflow.org/api_tflite/0.0.1-alpha.4/
• Body segmentation: robust-video-matting

WebGPU

Experimental support only until support is officially added in Chromium

• Performance issues: https://github.com/tensorflow/tfjs/issues/5689

Known Issues

Face Detection

Enhanced rotation correction for face detection is not working in NodeJS due to missing kernel op in TFJS
Feature is automatically disabled in NodeJS without user impact

• Backend NodeJS missing kernel op RotateWithOffset
  https://github.com/tensorflow/tfjs/issues/5473

Body Detection

MoveNet MultiPose model does not work with WASM backend due to missing F32 broadcast implementation

• Backend WASM missing F32 broadcat implementation
  https://github.com/tensorflow/tfjs/issues/5516

Object Detection

Object detection using CenterNet or NanoDet models is not working when using WASM backend due to missing kernel ops in TFJS

• Backend WASM missing kernel op Mod
  https://github.com/tensorflow/tfjs/issues/5110
• Backend WASM missing kernel op SparseToDense
  https://github.com/tensorflow/tfjs/issues/4824
