Image vectorization and editing via linear gradient layer decomposition

This is the source code of the paper: Image vectorization and editing via linear gradient layer decomposition, authors: Zheng-Jun Du, Liang-Fu Kang, Jianchao Tan, Yotam Gingold, Kun Xu. Please fell free to contact us if you have any questions, email: [e-mail]

Requirements

Windows 10
Microsoft Visual Studio 2019
OpenCV 4.1.2 or higher version
Nlopt 2.4.2 (included in "ImageVectorization/ThirdParty")
autodiff (included in "ImageVectorization/ThirdParty")
Python 3.7 (used to generate vector graph with .svg format)

Directories

1. Data: we provide 10 examples in this directory
2. ImageVectorization： main program for layer deomposition
3. ProcessRegionSegImg: preprocess the region segmentation input
4. Gen_svg_script: contain a python script to generate the vector graph

Usage

1. Open "./ImageVectorization" -> click ImageVectorization.sln -> run "main.cpp". It will automatically decomposes the input image into a set of layers and savea the results in "data/xxx/results".

   If you want to test your examples, you could use the "ProcessRegionSegImg" project to preprocess your segmentation images first.

2. Run "Gen_svg_script/main.py" to generate the vector graph with .svg format.
