Hair Segmentation Realtime using Keras

The architecture was inspired by Real-time deep hair matting on mobile devices

Prerequisites

python 3.6 tensorflow-gpu==1.13.1, opencv-python==4.1.0.25, Keras==2.2.4, numpy==1.16.4, scikit-image==0.15.0

install environment in conda:

conda env create -f environment.yml

Dataset

• CelebAMask-HQ (contain 29.300 images and masks hair segmentation)
• Figaro-1k
• Lft

Download data CelebAMask-HQ and use preprocess in ./data/pre-process-data-CelebAMask-HQ.ipynb to create dataset

Train model

python train.py [--datadir PATH_FOLDER] [--batch_size BATCH_SIZE] [epochs EPOCHS] [--lr LEARNING_RATE] []

optional arguments:
    --datadir:        path to folder dataset, default ./data
    --batch_size:     batch size training, default 4
    --epochs:         number of eposchs, default 5
    --lr:             learning rate, default 1e-4
    --image_size:     size image input, default (224, 224)
    --use_pretrained: use pretrained, default false
    --path_model:     directory is saved checkpoint, default ./checkpoints
    --device:         device training model, default 0 (GPU:0), 1(GPU:1), -1(CPU)          

Evaluate model

python evaluate.py

Run pretrain model

# Run test.py
python demo.py

You will see the predicted results of test image in test/data

Result

Convert to Tensorflow Lite

• Convert

# Convert Model to Mobile
python convert_to_tflite.py

• Show shape model tflite

# Shape input and output shape model tflite 
python shape_input_output_tflite.py

About Keras

Keras is a minimalist, highly modular neural networks library, written in Python and capable of running on top of either TensorFlow or Theano. It was developed with a focus on enabling fast experimentation. Being able to go from idea to result with the least possible delay is key to doing good research.

Use Keras if you need a deep learning library that:

allows for easy and fast prototyping (through total modularity, minimalism, and extensibility). supports both convolutional networks and recurrent networks, as well as combinations of the two. supports arbitrary connectivity schemes (including multi-input and multi-output training). runs seamlessly on CPU and GPU. Read the documentation Keras.io

Keras is compatible with: Python 3.6.

TODO

• Implement model using Keras
• Convert model to Tensorflow Lite
• Implement model to Android (DOING)
