Basic Image AlgorithmS (BIAS) Library

This is the BIAS (Basic Image AlgorithmS) library. It is a code base for research and software development of computer vision, motion estimation and 3d reconstruction algorithms.

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 OpenGL/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.
