New release of OpenViBE 0.11.0 available

Post by lbonnet »

The OpenViBE development team is happy to announce the release of OpenViBE 0.11.0 "Summer Edition", available for download at : http://openvibe.inria.fr/?q=download

This release brings many exciting features, including three community contributions :

Aurélien Van Langhenhove contributed a driver based on OpenAL to acquire sound signal from microphone input.

Joan Fruitet patched the Matlab Filter box, by fixing bugs and adding stimulation output.

Olivier Rochel contributed bugfix patches, for matlab box and skeleton-generator.

Motor-imagery and SSVEP scenarios now use CSP for higher performances.
Emotiv driver was updated to make gyroscope values available.
Signal Concatenation box has been rewritten for fast file concatenation.
The developer tool Skeleton-Generator benefited from a major update.
Matlab box outputs stimulations.
Channel Selector and Reference Channel feature smart channel selection (names, indexes, ranges).
... and more new features detailed below.

Many thanks to Aurélien, Joan and Olivier for their contributions! If you are interested in joining the effort feel free to contact us!

Full feature list :

== COMMUNITY ==
+ Aurélien Van Langhenhove contributed a driver based on OpenAL to acquire sound signal from microphone input.
+ Joan Fruitet contributed a patch for the Matlab filter box, by fixing bugs and adding stimulation output.
+ Olivier Rochel contributed patches for the skeleton-generator and the matlab box

== SUPPORT ==
+ OpenViBE is now officially supported on Fedora 15, Ubuntu 11.04 and Windows 7 64bit.

== APPLICATIONS ==
* The Emotiv EPOC driver now acquires values from gyroscope sensors (new option in the driver properties).
* The Player in the OpenViBE Designer can now be controlled with keyboard shortcuts (F5: stop, F6: one-step, F7: play, F8: fast-forward)
* Skeleton Generator benefited from a major update, and can produce box skeleton with Listeners, Codecs, Flags, etc.

== PLUGINS ==
+ New Reference Channel and Channel Selector boxes. The older boxes are now deprecated. The channel selection is smarter (name or 1-based index, 'X:Y' for channel range).
+ New Signal Concatenation box. The older box is now deprecated. The concatenation is much faster, and end-of-file is detected automatically through a time-out.
+ New Stream Switch box that copies its input chunks on one of its outputs. The active output is selected with defined stimulations.
* CSV file writer can receive 1 or 2-dimensional matrices
* Matrix display can receive 1 or 2-dimensional matrices
* The Matlab filter box has now a Stimulation output, and the Matlab messages are redirected to the OpenViBE console (warnings, errors, disp, etc.)
* Classifier Trainer outputs standard deviation along with classification percentage on the k-fold test. k-fold test now randomize the input data prior to testing by default.
* CSP and xDAWN spatial filter trainers output a stimulation OVTK_StimulationId_TrainCompleted after a successful training.
* Classifier Accuracy visualization box can now show score and/or percentages, or none of them.

== RESOURCES ==
+ New set of scenarios for a Motor-Imagery based BCI using CSP spatial filters, and demonstrating how to measure classifier performances offline or online (confusion matrix, overall performance).
+ Documentation for the Matlab Filter box.
+ Documentation for the Display-Cue visualisation box.
* SSVEP scenarios now make use of CSP spatial filters for better performances.
* Acquisition Server documentation updated to latest GUI modification (division driver properties/server settings)

----------------------------------
==== 0.11.0 CHANGELOG ====
----------------------------------
Released 11th August 2011

=== KERNEL AND UTILITIES ===

openvibe :
+ added possibility for master kernel context when creating a kernel context
* replaced "-" range separator with ":" range separator (for later use of the "-" char as a reversed index in the channel selector)

openvibe-kernel :
+ sent that master kernel context to the managers
+ added warning message when adding box an input or output with unknow stream type
+ added new configuration token Kernel_AllowUnregisteredNumericalStimulationIdentifiers to allow numerical stimulation ids to be expanded from settings - default is disabled
+ added a configuration token Plugin_Classification_RandomizeKFoldTestData (default to true) to control the randomization behavior of the classifier trainer
* ovkCScenarioImporterContext.h: removed the "mutable" keyword for the scenario member (reference) > mutable reference useless, and not allowed by GCC 4.6 (fedora 15 compatibility issue)

openvibe-toolkit :
+ Templated codecs : added acquisition stream decoder
* ovtkTDecoder.h : added an optional argument in decode(..) to tell whether to markInputAsDeprecated or not.
* added a function to get the number of labels a feature vector set owns - can be used by classifier algorithms to check they have appropriate number of labels to be trained
* Templated codecs : virtualized destructors so that destrucion mechanism works properly

* Coding rules & naming convention should be respected
* French comments & trace messages should be either removed or translated in english and sent to the Log Manager
* ...
Please care about the ecosystem !
+ created basic tree for mgoyat's contrib
+ added folders to match mgoyat' tree structure
