# SURF - Speeded Up Robust Features This is the original source code or SURF, [Speeded Up Robust Features](https://www.vision.ee.ethz.ch/~surf/eccv06.pdf) ## Requirements The library has been compiled using g++, version 4.0.2, for usage on a machine Pentium 4 or better. To use the library in your program, you need to use the same compiler version. Update: You can compile it for your architecture. Please find the sources in `SURF-source` If you require the library to be compiled using another compiler, or another platform (such as Athlon XP), please contact us. ## Usage Execute surf.ln without any argument in order to get more information concerning the usage and possible parameters. Use "make match.ln" to compile the matching demo application. ## Data Format The output format of SURF is as follows: (1 + length of descriptor) number of points x y a b c l des x y a b c l des ... x, y = position of interest point a, b, c = [a b; b c] entries of second moment matrix. SURF only has circular regions, hence b = 0; a = c -> radius = 1 / a^2 l = sign of laplacian (-1 or 1) des = descriptor vector itself ## Data Input Format If only the SURF descriptor should be computed, the -p1 command can be used. As an argument, it takes a file of the following format: (dummy byte) number of points x y a b c x y a b c Where, as above, [a b; b c] forms the second moment matrix. Note that SURF uses circular regions. Hence, a = c and b = 0. ## Licensing conditions This software is being made available for research purposes only. It is necessary to obtain a license (see LICENSE file) for commercial applications.
