Handwriting generation

This project is a web app (CopyMonkey) which uses machine learning to mimic your handwriting style like a monkey. Have fun generating handwriting in your own style!

Demo: https://youtu.be/Ghsb3w0QACI

The ML model is implemented from "Generating Sequences With Recurrent Neural Networks" by Alex Graves (https://arxiv.org/abs/1308.0850)

How to run the web app on your local machine

git clone https://github.com/swechhachoudhary/Handwriting-synthesis.git
cd Handwriting-synthesis
python3 -m venv hand_gen_env
source hand_gen_env/bin/activate
pip install -r requirements.txt
python main.py

How to train handwriting generation (synthesis) model

python train.py --n_epochs 120 --model synthesis --batch_size 64 --text_req

How to train handwriting prediction model

python train.py --n_epochs 120 --model prediction --batch_size 64

Data description:

There are 2 data files that you need to consider: data.npy and sentences.txt. data.npycontains 6000 sequences of points that correspond to handwritten sentences. sentences.txt contains the corresponding text sentences. You can see an example on how to load and plot an example sentence in example.ipynb. Each handwritten sentence is represented as a 2D array with T rows and 3 columns. T is the number of timesteps. The first column represents whether to interrupt the current stroke (i.e. when the pen is lifted off the paper). The second and third columns represent the relative coordinates of the new point with respect to the last point. Please have a look at the plot_stroke if you want to understand how to plot this sequence.
