Diffusion Curve Renderer

C++ project for reconstructing images using Bézier curves and color diffusion constrained by those curves.

Inspired by the work of Orzan et al.. Vectorization algorithms are adapted from this repository.

Features

• Image reconstruction with Bézier curves
• Color diffusion along vectorized curves
• Vectorization algorithms for curve extraction
• Modern GUI with ImGui and Qt
• Uses OpenGL for rendering

Dependencies

All dependencies are included in the Libs folder:

• ImGui: For the graphical user interface
• OpenCV: For edge detection (built with MSVC 2019 64-bit)
• Eigen: For vectorization and linear algebra

Build Instructions

1. Install CMake 3.25.1 or newer.
2. Install Visual Studio 2022 with the MSVC C++ v143 Compiler.
3. Install Qt 6.7.3 MSVC2022 64bit.
4. Set the environment variable Qt6_DIR to C:\Qt\6.7.3\msvc2022_64.
5. Clone the repository: cmd git clone https://github.com/berkbavas/DiffusionCurveRenderer.git
6. Create and enter the build directory: cmd mkdir Build cd Build
7. Run CMake: cmd cmake ..
8. Open DiffusionCurveRenderer.sln in Visual Studio 2022.
9. Build and run the project.
