Davis King 0f9f0e7733 Moved the point/vector rotation/transformation code into its own file. 2012-12-11 21:18:57 -05:00
Davis King a30fa632fa Made the functions for scaling, rotating, and generally transforming images 
more general.  Previously they required the user to use the same type of image
for both input and output.  This has been relaxed so now different typed images
can be used.

 2012-12-10 23:25:17 -05:00
Davis King 0da136b0df Added an overload of draw_image() that's useful for drawing images 
and doing interpolation at the same time.

Davis King 7b43a3c6ac All I did in this change was switch from using #include "" syntax 
to #include <> syntax.
 2012-12-08 09:32:13 -05:00
Davis King 953fbe1772 Made the docs better in how they display the "file to include" and also example 
program lists
 2012-12-08 09:17:01 -05:00
Davis King b80edc8839 Fixed confusing error message. 2012-12-05 23:14:20 -05:00
Davis King 55d21096de Changed the feature extraction interfaces for the sequence labeling and 
assignment problem learning tools to also include an optional
num_nonnegative_weights() method.  This method can be used to tell any machine
learning tools which elements of the learned parameter vector should be
non-negative.  As part of this change, I also removed the previous methods for
doing this from the structural_assignment_trainer since they are now redundant.

Davis King 3956330d1f simplified examples 2012-12-05 19:36:39 -05:00
Davis King 0c0db073cb Added a version of print_options() that doesn't take an ostream but just prints 
to cout.

Davis King 4855666797 Added a pragma to disable a warning from visual studio 2012. 2012-11-25 19:52:32 -05:00
Davis King 484e8a3d73 Reduced the number of tests because otherwise we get really close to the limit on the number 
of TCP connections in the TIME_WAIT state on Windows XP.  This results in the tests failing
if you run them multiple times within the TIME_WAIT timeout period.  So this change makes
the tests less likely to false alarm when run on Windows XP.

Davis King ec79a93771 Made the svm_c_linear_trainer use the risk gap to decide when to stop. So now 
it interprets its epsilon parameter the same way the other OCA based SVM tools
in dlib do.  It also has a more intuitive interpretation than the previous
stopping condition.
