Davis King efd945618d Minor update 2017-12-18 16:20:21 -05:00
Davis King 603ebc2750 Changed this example to use repeat layers. This doesn't change the behavior of 
the code, but it helps visual studio use less RAM when building the example,
and might make appveyor not crash.  It's also a
slightly cleaner way to write the code anyway.

Davis King e273f5159d Added find_min_global() overloads. 2017-12-02 07:53:31 -05:00
Davis King 15c04ab224 This example still uses a lot of visual studio ram. 2017-12-01 00:26:31 -05:00
Davis King 2b3d8609e5 These examples compile now in visual studio due to the recent pragma directive added to core.h. 2017-11-30 22:38:29 -05:00
Davis King 4fa32903a6 clarified docs 2017-11-25 19:28:53 -05:00
Davis King 4d0b203541 Just moved the try block to reduce the indentation level. 2017-11-25 12:25:35 -05:00
Davis King 929870d3ad Updated example to use C++11 style code and also to show the new find_max_global() routine. 2017-11-25 12:23:43 -05:00
Davis King 1aa6667481 Switched this example to use the svm C instead of nu trainer. 2017-11-25 08:26:16 -05:00
Davis King 04991b7da6 Made this example program use the new find_max_global() instead of grid search 
and BOBYQA.  This greatly simplifies the example.

Amin Cheloh 1798e8877c Update dnn_mmod_find_cars2_ex.cpp (#966) 2017-11-17 06:38:48 -05:00
Davis King b84e2123d1 Changed network filename to something more descriptive. 2017-11-15 07:10:50 -05:00
Juha Reunanen e48125c2a2 Add semantic segmentation example (#943) 
* Add example of semantic segmentation using the PASCAL VOC2012 dataset

* Add note about Debug Information Format when using MSVC

* Make the upsampling layers residual as well

* Fix declaration order

* Use a wider net

* trainer.set_iterations_without_progress_threshold(5000); // (was 20000)

* Add residual_up

* Process entire directories of images (just easier to use)

* Simplify network structure so that builds finish even on Visual Studio (faster, or at all)

* Remove the training example from CMakeLists, because it's too much for the 32-bit MSVC++ compiler to handle

* Remove the probably-now-unnecessary set_dnn_prefer_smallest_algorithms call

* Review fix: remove the batch normalization layer from right before the loss

* Review fix: point out that only the Visual C++ compiler has problems.
Also expand the instructions how to run MSBuild.exe to circumvent the problems.

* Review fix: use dlib::match_endings

* Review fix: use dlib::join_rows. Also add some comments, and instructions where to download the pre-trained net from.

* Review fix: make formatting comply with dlib style conventions.

* Review fix: output training parameters.

* Review fix: remove #ifndef __INTELLISENSE__

* Review fix: use std::string instead of char*

* Review fix: update interpolation_abstract.h to say that extract_image_chips can now take the interpolation method as a parameter

* Fix whitespace formatting

* Add more comments

* Fix finding image files for inference

* Resize inference test output to the size of the input; add clarifying remarks

* Resize net output even in calculate_accuracy

* After all crop the net output instead of resizing it by interpolation

* For clarity, add an empty line in the console output

Davis King 50de3da992 Updated comments to reflect recent API changes. 2017-11-02 05:43:15 -04:00
Davis King dc0245af05 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.

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.

MambaWong 373ca59369 Update webcam_face_pose_ex.cpp (#702) 
Test on a given video like this cv::VideoCapture cap("Sample.avi") may be broken when the video frames are not enough before the main window is closed by the user.

Davis King 64052a3ff1 Added a comment 2017-07-02 08:43:45 -04:00
Davis King f5574434db Upgraded loss_mmod_ to support objects of varying aspect ratio. This changes 
the API for the mmod_options struct slightly.
 2017-07-01 14:46:27 -04:00
Davis King 17b48b97bb Changed the random_cropper's interface so that instead of talking in terms of 
min and max object height, it's now min and max object size.  This way, if you
have objects that are short and wide (i.e. objects where the relevant dimension
is width rather than height) you will get sensible behavior out of the random
cropper.

Davis King 334ba38ec6 A minor change to hopefully reduce inane warnings from visual studio. 2017-05-14 20:07:16 -04:00
