Introduction

The Basic Image AlgorithmS C++ Library (BIAS) is the code base for research and software development of computer vision, motion estimation and 3d reconstruction algorithms.

History

Kick off development started in 2001 performed by the students and research assistants at the Multimedia Information Processing Group at Kiel University, Germany (Prof. Dr.-Ing. R. Koch). However, with more than 200.000 lines of code today several researchers and application developers are using and developing the library world wide giving back very helpful contributions.

Features

Main features of this library include image processing, motion estimation and 3D reconstruction related algorithms, e.g.

• basic image i/o jpg,pnm,exr,tif,... (and more if third party libraries such as Imagemagick are available)
• feature extraction, tracking and image filtering and warping
• projective geometry, representation of mathematical entities, estimation algorithms, e.g. for fundamental matrix
• basic mathematical tools, e.g. for solving linear and non-linear equation systems, minimization, RANSAC,
• different camera models (fish-eye, radial/tangential distortion, spherical, cylindrical)
• Gui and 3D GL/VRML support etc.

BIAS works on PC platforms on Linux (with gcc) and natively on MS Windows (with Microsoft compiler). Please look at the following pages for details.

How to get it

• BIAS Release downloads, nightly snapshots

• At 01.November 2008 we migrated our VCS from CVS to Bazaar. Unfortunately there is no anonymous repository access any more. If you desperately want access you can try and ask us.
• Please use the nightly Bazaar snapshots to stay up to date. (link)
