PixieToon

PixieToon is an Android application that transforms your photos into cartoon-like images using a machine learning model. This project serves as a demonstration of how to integrate a TensorFlow Lite model into an Android app.

Features

• Select an image from your device’s gallery.
• Apply a cartoonization effect to the selected image.
• Save the cartoonized image to your device.

How It Works

Below are screenshots demonstrating the main steps of using PixieToon:

Machine Learning Model

The cartoonization effect is achieved using a pre-trained TensorFlow Lite model (cartoon_model.tflite). This model is an implementation of the White-Box cartoonization method described in the following paper:

The model is included in the app/src/main/assets directory.

Project Structure

This project follows the standard structure for an Android application built with Gradle. Here’s a brief overview of some important files and directories:

• settings.gradle.kts: This is the main settings file for the Gradle build, which includes all the sub-projects (modules) that are part of the project.
• build.gradle.kts (Project: PixieToon): This is the top-level build file that contains the configuration options that are common to all the sub-projects/modules.
• app/build.gradle.kts (Module: app): This file contains the specific build configurations for the app module, such as dependencies, application ID, and version codes.
• app/src/main: This directory contains the main source code for the application.
  • AndroidManifest.xml: The manifest file for the application.
  • java/: Contains the Kotlin and Java source code.
  • res/: Contains all the non-code resources, such as layouts, drawables, and strings.
  • assets/: Contains the TensorFlow Lite model (cartoon_model.tflite) and a test image (test_image.jpg).

Building from Source

To build the project from the source code, follow these steps:

1. Clone the repository:

   git clone https://gitlab.com/rokorolev/pixietoon.git
   

2. Open the project in Android Studio.
3. Let Android Studio sync the project with Gradle.
4. Build and run the application on an Android device or emulator.
