说明： 一种特征描述算子，功能和sift类似，但比sift速度更快，有重要的研究价值
(A characterization of operators, functions and sift similar, but faster than sift, has important research value)

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.
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
