# Sign language recognition with RNN and Mediapipe
#### with multi hand tracking
Sign language gesture recognition using a reccurent neural network(RNN) with Mediapipe hand tracking.
This project is for academic purpose. Thank you for Google's Mediapipe team :)
### Data Preprocessing with Mediapipe (Desktop on CPU)
Create training data on Desktop with input video using [Multi Hand Tracking](https://github.com/google/mediapipe/blob/master/mediapipe/docs/multi_hand_tracking_mobile_gpu.md).
Gesture recognition with deep learning model can be done with **hand landmark features** per frame with RNN training .
**CUSTOMIZE:**
- Use video input instead of Webcam on Desktop to train with video data
- Preprocess hand landmarks for every frame per one word and make it into one txt file
### 1. Set up Hand Tracking framework
* Install Medapipe
```shell
git clone https://github.com/google/mediapipe.git
```
See the rest of installation documents [here](https://mediapipe.readthedocs.io/en/latest/install.html).
* Change **end_loop_calculator.h** file
```shell
cd ~/mediapipe/mediapipe/calculators/core
rm end_loop_calculator.h
```
to our new /end_loop_calculator.h file in the modified_mediapipe folder.
* Change **demo_run_graph_main.cc** file
```shell
cd ~/mediapipe/mediapipe/examples/desktop
rm demo_run_graph_main.cc
```
to our new demo_run_graph_main.cc file in the modified_mediapipe folder.
* Change **landmarks_to_render_data_calculator.cc** file
```shell
cd ~/mediapipe/mediapipe/calculators/util
rm landmarks_to_render_data_calculator.cc
```
to our new landmarks_to_render_data_calculator.cc file in the modified_mediapipe folder.
### 2. Create your own training data
Make **train_videos** for each sign language word in one folder. Use **build.by** file to your mediapipe directory.
* Usage
To make mp4 file and txt file with mediapipe automatically, run
```shell
python build.py --input_data_path=[INPUT_PATH] --output_data_path=[OUTPUT_PATH]
```
inside mediapipe directory.
IMPORTANT: Name the folder carefully as the folder name will be the label itself for the video data.
(DO NOT use space bar or '_' to your video name ex) Apple_pie (X))
For example:
```shell
input_video
├── Apple
│ ├── IMG_2733.MOV
│ ├── IMG_2734.MOV
│ ├── IMG_2735.MOV
│ └── IMG_2736.MOV
└── Happy
├── IMG_2472.MOV
├── IMG_2473.MOV
├── IMG_2474.MOV
└── IMG_2475.MOV
...
```
The output path is initially an empty directory, and when the build is complete, Mp4 and txt folders are extracted to your folder path.
Created folder example:
```shell
output_data
├── Absolute
│ └── Apple
│ ├── IMG_2733.txt
│ ├── IMG_2734.txt
│ ├── IMG_2735.txt
│ └── IMG_2736.txt
| ...
├── Relative
│ └── Apple
│ ├── IMG_2733.txt
│ ├── IMG_2734.txt
│ ├── IMG_2735.txt
│ └── IMG_2736.txt
│ ...
└── _Apple
├── IMG_2733.mp4
├── IMG_2734.mp4
├── IMG_2735.mp4
└── IMG_2736.mp4
```
Your contribution is welcome [here](https://github.com/rabBit64/Sign-language-recognition-with-RNN-and-Mediapipe/tree/master/ASL)!
### 3. Train RNN model
* Train
```shell
python train.py --input_train_path=[INPUT_TRAIN_PATH]
```
INPUT_TRAIN_PATH is the path to the output folder in the previous step. (either Relative or Absolute path) The model is saved as 'model.h5' in the current directory.
