MetaMorph: AI Assistance to Transform Lo-Fi Sketches to Higher Fidelities

MetaMorph is an AI tool to detect the constituent UI elements of low fidelity prototype sketches.

---

Dataset

MetaMorph uses

• UISketch
• Syn dataset

---

Setup and usage

MetaMorph API uses Python 3.6 and Tensorflow Object Detection API (TFOD).

To install and use MetaMorph API, follow the steps below

• Download the following files to the models/ directory

  • frozen_inference_graph.pb
  • labels.json

• Install poetry

  pip install poetry

• Upgrade pip, as older version of pip causes installation issue with opencv

  poetry run pip install --upgrade pip
  

• Install dependencies

  poetry install

• Run the API

  poetry run python app.py

---

Docker

MetaMorph API can be quickly deployed from docker without any installation or model download steps.

To use it, pull the image from dockerhub at vinothpandian/metamorph

docker pull vinothpandian/metamorph:latest

Run it with docker the following command

docker run -p 8000:8000 --name metamorph vinothpandian/metamorph:latest

---

Development

To retrain or further improve MetaMorph model

Installation

• Install Tensorflow Object Detection API using this installation guide.

• Copy the config file from configs folder or setup your own Tensorflow Object Detection API Model with config

• Download the UISketch dataset from Kaggle.

• Generate synthetic data

  poetry run python syn_datagen.py -d /path/to/uisketch -o /path/to/tfod/object_detection -l no.of.sketches

  To check more options on data generation use poetry run python syn_datagen.py --help

• Follow the guide from training and evaluation guide by TFOD team.
