Vtracer
vtracer is a raster to SVG converter and image vectorization pipeline. It transforms high-resolution scans and pixel-based images into scalable vector graphics by tracing shapes and colors.
The tool includes a specialized pixel art vectorizer that converts low-resolution raster graphics into vector shapes while preserving a pixelated aesthetic. It also functions as a Bezier curve fitting tool to simplify dense point sets into smooth curves, reducing the complexity of vector paths.
The project covers large scale image vectorization for gigapixel-scale data, color clustering and patch segmentation, and vector path optimization to reduce node counts. It allows for the organization of sequential image processing stages into reusable workflows.
