Davis King f88fd99ed4 Make cmake output less confusing 2017-10-27 23:42:40 -04:00
Davis King c29314f34a Clarified build instructions 2017-10-27 23:39:04 -04:00
Davis King 1e877b1917 Changed graph construction for chinese_whispers() so that each face is always 
included in the edge graph.  If it isn't then the output labels from
chinese_whispers would be missing faces in this degenerate case.  So basically this fixes a bug
where chinese_whispers(), when called from python, would sometimes return a labels array
that doesn't include labels for all the inputs.

Davis King 347257cbc0 Made random_cropper use cleaner and unbiased dlib::rand interface. 2017-10-27 07:27:57 -04:00
Davis King faf8676a49 Cleanup 2017-10-27 05:58:34 -04:00
Davis King e8d74b3015 Removed old cruft not needed anymore since we are doing this kind 
of thing with cmake targets already in set_compiler_specific_options.cmake.

Sean Warren 16ad749c45 Win lapack (#913) 
* Fall back on find_package for blas, lapack on Windows

* Remove debugging message
 2017-10-27 05:45:53 -04:00
Davis King aa93c8f861 Updated python code to use the new dlib::jitter_image() instead of hacking it 
out of the random_cropper.
 2017-10-25 05:42:31 -04:00
Davis King e338bf02e0 Changed the random_cropper's set_min_object_size() routine to take min box 
dimensions in the same format as the mmod_options object (i.e. two lengths
measured in pixels).  This should make defining random_cropping strategies that
are consistent with MMOD settings much more straightforward since you can just
take the mmod_options settings and give them to the random_cropper and it will
do the right thing.

Sean Warren 45ce9f7b6d Use banded Cholesky factorization if possible (#857) 
* Use banded Cholesky factorization if possible
Computation cost from n.n.n -> n.n.b where b is band size

* Tidy up whitespace

* Remove typo

*  Escape from banded matrix detection correctly

* Use LAPACK banded Cholesky factorisation where possible

* Add banded chol tests

* Add test for banded chol in column major layout

* Use row major layout for banded chol - more efficient as we will pass to LAPACK

Davis King 04a8f0093d Make sure the test loss the trainer logs to the console never gets suck at 
infinity.

Gilles Rochefort 540f47409e Missing interfaces in add_prev for compatibility with mmod loss. (#901) 2017-10-20 21:44:00 -04:00
Davis King 6d343f93da Sometimes the loss_mmod_ layer could experience excessively long runtime during 
early iterations since the model might produce a huge number of false alarms
while the detector is still bad.  Processing all these detections can cause it
to run slowly until the model is good enough to avoid really excessive amounts
of false alarms.  This change puts more of a limit on the number of false
alarms processed during those early iterations and avoids the slowdown.
 2017-10-20 21:37:54 -04:00
Davis King 3e48a36ede The loss returned by compute_loss_value_and_gradient() wasn't quite right. It 
doesn't effect normal use, but it's still wrong and this change fixes it.

Davis King 1d8445cbfd Fixed the terrible breaking change to the tensor object I made earlier today :( 2017-10-19 20:57:24 -04:00
Davis King 86465e307a Improved cmake error messages about CUDA support. 2017-10-19 12:09:29 -04:00
Davis King e9837f7035 Changed tensor so that, when reallocating memory, it frees any existing memory 
*before* allocating new memory.  It used to be the other way around which
caused momentary spikes of increased memory usage.  This could put you over the
total memory available in some cases which is obviously less than ideal
behavior.

Davis King 08a7483724 I accidentally slightly changed the cropping behavior of 
get_face_chip_details() when used with the 68 point landmark model about a
month ago.  This change reverts it back to the previous behavior.  The change
was very minor, so it shouldn't matter either way.  But being consistent is
important and I'm changing it back.
