This project implements a non-photorealistic rendering technique to automatically generate line drawings from photographs, offering both a real-time interactive GUI and a command-line interface. It is targeted at researchers and users interested in image processing and artistic rendering.

How It Works

The core of the project is based on the technique described by Kang et al., which focuses on generating coherent line drawings. It likely employs algorithms for edge detection, line thinning, and coherence enhancement to produce stylized line art from input images. The GUI version provides an interactive experience, while the command-line version allows for batch processing and integration into other workflows.

Quick Start & Requirements

• Build: Requires C++17, CMake, OpenCV 3. WxWidget 3 is needed for the GUI. A build.sh script is provided for Linux.
• Pre-built: Windows and macOS versions are available for download.
• Command Line Usage: src/cmd.cpp is the entry point. Example options include -s for source image and -o for output path, with parameters for ETF kernel size, iteration counts, and line width.
• Documentation: Usage examples are available in test.sh.

Highlighted Details

• Provides both a real-time interactive GUI and a command-line application.
• Supports C++11 via a dedicated branch.
• Cross-platform compatibility (Windows, Linux, macOS).
• Configurable parameters for line drawing generation (e.g., sigma_c, sigma_m, rho).
