VLFeat is a cross-platform open source collection of vision algorithms with a special focus on visual features (for instance SIFT and MSER) and clustering (k-means, hierarchical k-means, agglomerative information bottleneck). It bundles a MATLAB toolbox, a clean and portable C library and a number of command line utilities. Thus it is possible to use the same algorithm both from MATLAB, the command line, and your own programs.

Many parties make the development of VLFeat possible:

## Sponsors

In 2012 the development of VLFeat is supported by the PASCAL Harvest programme. Several people have been working in Oxford to add new functionalities to the library. Moreover, leading researchers in computer vision were consulted as advisors of the project. Some of these advancements have been presented at a tutorial at the European Conference in Computer Vision (ECCV) 2012. See the PASCAL Harvest Roadmap for further details.

## Team

VLFeat is developed by a team of computer vision researchers, including master and PhD students, postgraduates, and senior researchers, as listed below. VLFeat was created by Andrea Vedaldi and Brian Fulkerson in 2007, based on previously published software by the same authors.

Andrea Vedaldi joined the faculty at the University of Oxford in 2012. Since 2008 he was junior research fellow in the Oxford Visual Geometry Group. He received the Ph.D. and Master's degrees in Computer Science from the University of California - Los Angeles, in 2008 and 2005, and the Bachelor's degree in Information Engineering from the University of Padova, Italy, in 2003. He is the recipient of the UCLA outstanding Master's and Ph.D. awards.

Brian Fulkerson received his B.S. in Computer Engineering from the University of California - San Diego in 2004, and his M.S. and Ph.D. in Computer Science from the University of California - Los Angeles Vision Lab in 2006 and 2010.

Karel Lenc received his B.S. degree in Cybernetics and Measurements from the Czech Technical University in 2010. He is currently pursuing M.S. degree in Computer Vision and Computer Engineering at the CTU, Center for Machine Perception. He visited the Department of Engineering Mathematics, University of Bristol in 2011 and the Oxford Visual Geometry Group in 2012.

Daniele Perrone received his B.S. degree in Computer Engineering from Università della Calabria in 2007, and his M.S. degree in Artificial Intelligence from "Sapienza" Università di Roma in 2009. He started his Ph.D. in June 2010 at Heriot-Watt University, Edinburgh, UK. From June 2012 he joined the Computer Vision Group at the Universität Bern, Switzerland.

Michal Perdoch received his Bachelor's degree in Software Engineering from the Slovak University of Technology in Bratislava in 2001, Master's degree in Computer Science and Ph.D. degree in Artificial Intelligence and Biocybernetics from the Czech Technical University in Prague, in 2004 and 2011. He is currently a postdoctoral researcher at the CTU Center for Machine Perception.

Milan Sulc received his Bachelor's degree in Cybernetics and Robotics from the Czech Technical University in 2012. He is currently pursuing Master degrees in Computer Vision and Artificial Intelligence at the CTU and Entrepreneurship and Commercial Engineering in Industry at CTU. He is a student intern at the CTU Center for Machine Perception.

Hana Sarbortova received her Bachelor of Engineering degree in Digital Signal and Image Processing from the University of Central Lancashire in 2012. She is currently studying Computer Vision and Digital Image at the Czech Technical University in Prague. She is a student intern at the CTU Center for Machine Perception.
