说明： SURF特征提取算法的演示程序，在大多情况下处理速度和精度都超过sift算法
(SURF feature extraction algorithm demo program, in most of the cases deal with the speed and accuracy of more than sift algorithm)

Usage
-----
The library has been compiled using g++, version 4.0.0, for usage on
a Pentium 4. To use the library in your program, you need to use
the same compiler version.
If you require the library to be compiled using another compiler, or
another platform (such as Athlon XP), please contact us.
When compiled, execute surf.ln without any argument in order to get more
information concerning the usage and possible parameters.
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 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.
