# To-Do list for Human library
## Work in Progress
- Switch to custom `tfjs` for main `human` ESM bundle
<br>
### Exploring
- 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>
<br><hr><br>
## Known Issues
- `tfjs.esm.d.ts` missing namespace `OptimizerConstructors`
- exports from `match` are marked as private
<br>
### 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>
