Superpixel Mesh

A tiny library to generate a mesh of superpixels from some image

This repo can be tested in your browser. See here, where additionally I have an explanation of what this thing can do.

Motivation

There are a pretty solid algos to generate superpixels, yet, I needed one that:

• Generates a polygon mesh.
• It is an optimal approximation.

Building

You need to have installed:

• Compiler with C++17 features available.
• ceres-solver (tested using version 2.0.0)

To build demo app, you also need

• OpenCV (tested using version 4.5.0, needed modules: core, highui, imgproc, imgcodec)

To enable unit tests:

• GTest

Running the sample app

demo_opencv /path/to/image.ext

Future work

• Multilevel mesh partioning, to allow faces with high error to be optimized separately.
