Davis King dbc9a815e2 Fixed an endianness bug in the PNG I/O functions which occurred when 16bit 
grayscale PNGs were used.  libpng doesn't automatically convert from host
endianness to big endian as the PNG standard demands.  You have to explicitly
tell it to do this or it will write out the 16bit pixel data in host order
which result in the wrong thing happening on little endian chips.  Similarly
for reading PNGs.

Davis King 33a192fc28 Fixed a bug pointed out by Joel Nelson in the version of md5() that took an 
istream.  The bug caused the function to crash on strings longer than 56
characters.

Davis King 9ab59297b2 Added the forces_last_weight_to_1() option to the svm_c_linear_trainer. 2013-01-03 22:15:27 -05:00
Davis King 96264d3339 Changed svm_c_linear_dcd_trainer so that when the user forces the last weight 
to 1 it automatically disables use of the bias since that is almost certainly
what the user will want to do.
 2013-01-03 22:02:16 -05:00
Davis King b445ddbd8d Switched this code to use the oca object's ability to force a weight to 1 
instead of rolling its own implementation.

Davis King 2461a5e16a Fixed spelling error in comment. 2012-12-28 19:19:00 -05:00
Davis King 1a6554bce5 merged 2012-12-28 19:14:58 -05:00
Davis King 68e88433fc Changed the spec for mutex::unlock() to say that it is illegal for a thread to 
unlock a dlib::mutex it doesn't own.  This is technically a non-backwards
compatible change to the API but it has always been implemented in a way that
didn't allow this kind of double unlock() on non-Windows platforms.
Additionally, the recent change to the dlib::mutex implementation on windows
also no longer allows this kind of double unlock.
 2012-12-28 19:14:31 -05:00
Davis King d5ca4a8b5b Changed the thread_pool so it uses auto_mutex::unlock() in the appropriate places 
instead of mutex::unlock().
 2012-12-28 19:02:38 -05:00

Davis King af7fcb0e09 Improved unit test repeatability. 2012-12-28 14:50:30 -05:00
Davis King 7087d75369 Switched the windows implementation of dlib::mutex to use a CRITICAL_SECTION instead 
of a "mutex" (i.e. the thing made by CreateMutex()) since a critical section does the
same thing but faster.
