Adaptive Superpixels

Copyright 2012-2014 by David Weikersdorfer

Adaptive Superpixels is a collection of superpixel algorithms for non-constant density functions.

Algorithms:

• Adaptive Superpixels for color images with a user-defined density function
• Depth-Adaptive Superpixels for RGB-D images
• SLIC for color images -- see ivrg.epfl.ch/research/superpixels

Examples

Installation

asp was tested under Ubuntu 14.04.

asp uses C++11 and requires an up to date compiler like GCC 4.8.x.

Requirements

• Build essential: sudo apt-get install build-essential g++ cmake cmake-qt-gui
• Eigen 3.x: sudo apt-get install libeigen3-dev
• slimage: Clone from https://github.com/Danvil/slimage (header only - no build required)
• OpenCV: sudo apt-get install libopencv-dev libasp itself does not require Qt or OpenCV, however the provided executable uses OpenCV to load and display images.

Installation instructions (Linux)

1. git clone git://github.com/Danvil/asp.git
2. cd asp; mkdir build; cd build
3. cmake-gui ..
4. Press 'Configure', select 'Unix Makefiles' and press 'Finish'. Change CMAKE_BUILD_TYPE to Release! Adapt the other variables accordingly. Press 'Generate' and close the cmake gui.
5. make

Things to try

• bin/asp --method SLIC --color ../examples/toy_color.png
• bin/asp --method ASP --color ../examples/toy_color.png --density ../examples/density_squares.pgm
• bin/asp --method DASP --color ../examples/toy_color.png --depth ../examples/toy_depth.pgm
