Short Abstract

StyleBlit is an efficient example-based style transfer algorithm that can deliver high-quality stylized renderings in real-time on a single-core CPU. Our technique is especially suitable for style transfer applications that use local guidance - descriptive guiding channels containing large spatial variations. Local guidance encourages transfer of content from the source exemplar to the target image in a semantically meaningful way. Typical local guidance includes, e.g., normal values, texture coordinates or a displacement field. Contrary to previous style transfer techniques, our approach does not involve any computationally expensive optimization.

Build / Installation

Like the demo above? ... try it by yourself!

This implementation is written in C++ using OpenGL3.2. Build scripts for web-app, MacOS desktop app, and Windows desktop app are provided.

Build StyleBlit as Web application

• We use Emscripten SDK to build the web app - to setup the Emscripten SDK, follow the instructions here: https://emscripten.org/docs/getting_started/downloads.html
• Once Emscripten SDK is configured (i.e., em++ command is found on your PATH and works), run build-emscripten.bat
• Run styleblit.html in your browser
• Possible issue: Google Chrome for security reasons might refuse to run html with emscripten code without http (file:///C:/.../styleblit.html), use different web browser or run it using HTTP server. For example python -m http.server 8000 (http://localhost:8000/styleblit.html)

Build StyleBlit for Windows

• Make sure you have Visual Studio installed (cl.exe compiler)
• Run build-windows.bat
• Run styleblit.exe

Build StyleBlit for MacOS

• Make sure you have clang compiler
• Run build-macos.sh
• Run styleblitapp
