matlab.

bot1131357 5089196e04 Check for __ARM_NEON__ for libpng (#679)
*  Added check to see if __ARM_NEON__ is defined. Now we can use the following command: cmake --build --config Release ..

* Rename to use_arm_neon.cmake to check_if_neon_available.cmake for clarity, minor tidying up of script, and simplifying try_compile() code for ARM NEON.

Juha Reunanen 4ec04bd51f Disable IntelliSense for all DNN unit tests (#678)
* Problem:    Visual Studio's vcpkgsrv.exe constantly uses a single CPU core,
            apparently never finishing whatever it's trying to do. Moreover,
            this issue prevents some operations like switching from Debug to
            Release (and vice versa) in the IDE. (Your mileage may vary.)
Workaround: Keep manually killing the vcpkgsrv.exe process.
Solution:   Disable IntelliSense for some files. Which files? Unfortunately
            this seems to be a trial-and-error process.

* Disable IntelliSense for the ResNet declarations

* Disable IntelliSense for even more stuff

* Disable IntelliSense for all DNN unit tests

Davis King 963e8e8266 Removed default argument from process_batch since it upsets older versions of
gcc and I can imagine scenarios where having it leads to user errors anyway.

Davis King 1928723aae Moved label_to_ignore into loss_multiclass_log_per_pixel_ and also cleaned up a
few minor things.

Juha Reunanen 4bc6c1e5b4 Add new loss layer for semantic segmentation (pixel-wise classification) (#540)
* #288 - add new layer loss_multiclass_log_matrixoutput for semantic-segmentation purposes

* In semantic segmentation, add capability to ignore individual pixels when computing gradients

* In semantic segmentation, 65535 classes ought to be enough for anybody

* Divide matrix output loss by matrix dimensions too, in order to make losses related to differently sized matrices more comparable
- note that this affects the required learning rate as well!

* Review fix: avoid matrix copy

* Review fix: rename to loss_multiclass_log_per_pixel

* Review fix: just use uint16_t as the label type

* Add more tests: check that network params and outputs are correct

* Improve error message when output and truth matrix dimensions do not match

* Add test case verifying that a single call of loss_multiclass_log_per_pixel equals multiple corresponding calls of loss_multiclass_log

* Fix test failure by training longer

* Remove the test case that fails on Travis for some reason, even though it works on AppVeyor and locally

Davis King 37a77ad86e Fixed broken copy constructor and assignment operator of con_, which became
broken about an hour ago.  Oops.

Davis King f5574434db Upgraded loss_mmod_ to support objects of varying aspect ratio. This changes
the API for the mmod_options struct slightly.

Davis King dcfff1c463 Added process() and process_batch() to add_loss_layer. These routines let you
easily pass arguments to any optional parameters of a loss layer's to_tensor()
routine.  For instance, it makes it more convenient to set loss_mmod_'s
adjust_threshold parameter.

Davis King 8eb9e295ee Made dnn_trainer sync its state to two separate sync files that it alternates
between.  This should make syncing more robust to sudden hardware failure that
happens right when saving to disk.

Davis King 31bcddd5e4 Cleaned up documentation for conv_. Also removed unnecessary tensor
reallocation and copying inside conv_'s backward pass.  Doing this
required adding an add_to_output boolean option to the methods of
tensor_conv.

Davis King 39be45ada2 Made is so pressing e in imglab toggles between views of the image where the
histogram is equalized or unmodified.  This way, if you are looking at
particularly dark or badly contrasted images you can toggle this mode and maybe
get a better view of what you are labeling.

Davis King ba72c2f95c Updated code to work with new random_cropper interface. 2017-06-18 08:11:54 -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 d2b80bfe6f Switched order of things in if statement so cmake hopefully won't give weird errors. 2017-06-06 05:47:00 -04:00
Davis King 74fbca45ca Changed the converter so that, rather than producing one python file with
everything in it, it now makes a python file as before but an additional binary
file with all the weights in it.  This way, if you are working with a network
with a very large number of weights you won't end up with a crazy large python
script.
