  • Upgraded support to OpenCV 2.4.0
  • Added pom.xml and assembly files for Maven support and changed the directory structure of the source code to match Maven's standard directory layout

March 29, 2012

  • Added new RealityAugmentor.ObjectSettings.surfaceHasTexture property to have ProCamTracker rectify the projector display on textureless surface planes, using either the FULL_FRAME or the centered HALF_FRAME of the camera image, specified by the roiAcquisitionMethod property
  • Renamed a few other Settings properties to reflect better their meanings

February 18, 2012

  • TrackingWorker now fully support tracking with OpenCL and OpenGL acceleration (when useOpenCL is checked)
  • New TrackingWorker.projectorBufferingSize (in number of frames to buffer) and proCamPhaseShift (in milliseconds) settings to compensate for the delay of the projector display, and of the camera capture as well, while still allowing processing at high FPS
  • Accelerated and parallelized execution of RealityAugmentor
  • Updated ObjectFinder adding useFLANN to its Settings properties, letting it use FLANN via OpenCV
  • Cleaned up and optimized HandMouse

  • New PS3EyeFrameGrabber from Jiri Masa can now grab images using the SDK from Code Laboratories
  • TrackingWorker now supports processing with OpenCL and OpenGL

October 1, 2011

  • Fixed DC1394FrameGrabber and FlyCaptureFrameGrabber to behave as expected with all Bayer/Raw/Mono/RGB/YUV cameras modes (within the limits of libdc1394 and PGR FlyCapture)

August 21, 2011

  • Upgraded support to OpenCV 2.3.1
  • OpenCVFrameGrabber now detects when CV_CAP_PROP_POS_MSEC is broken and gives up calling cvGetCaptureProperty()

July 5, 2011

  • Upgraded support to OpenCV 2.3.0
  • Fixed OpenKinectFrameGrabber and FFmpegFrameGrabber

June 10, 2011

  • New OpenKinectFrameGrabber to capture from Microsoft's Kinect stereo camera using OpenKinect
  • The Unix scripts now check for a 64-bit JVM in priority

May 11, 2011

  • Changed Marker.getCenter() back to the centroid, because it has better noise averaging properties and gives in practice more accurate results than the actual center
  • Added hack to OpenCVFrameGrabber.start() to wait for cvRetrieveFrame() to return something else than null under Mac OS X
  • Added to the scripts -Dapple.awt.fullscreencapturealldisplays=false Java option required for full-screen support under Mac OS X
  • Removed from the scripts the default -Dsun.java2d.opengl=True Java option, because since NVIDIA Release 260 family of drivers, most video drivers under Linux do not have good OpenGL support anymore
  • FFmpegFrameGrabber now works properly on Windows with newer binaries
  • New VideoInputFrameGrabber to capture using DirectShow, useful under Windows 7 where OpenCV and FFmpeg can fail to capture using Video for Windows
  • Changed the output of monitorWindows slightly to accommodate better the HandMouse

April 7, 2011

  • Added a format property to camera settings, mostly useful for FFmpegFrameGrabber, where interesting values include "dv1394", "mjpeg", "video4linux2", "vfwcap", and "x11grab"
  • Added hack to make sure the temporarily extracted library files get properly deleted under Windows
  • Added (rudimentary) outlier detection and modified zero threshold handling
  • Added new HandMouse and RealityAugmentor features
  • Fixed ProjectiveDevice.distort(), which mistakenly undistorted projector images instead

February 19, 2011

  • Upgraded to the latest version of JavaCV based on JavaCPP instead of JNA, featuring better performance
  • Enhanced a few things of the image alignment algorithm
  • Tried to fix image format conversion inside FlyCaptureFrameGrabber, but this is going to require more careful debugging

November 4, 2010

  • Renamed the package namespace to com.googlecode.javacv.procamtracker, which makes more sense now that JavaCV has been well anchored at Google Code for more than a year, piggybacking on the unique and easy-to-remember domain name, but this means you will need to manually edit any old XML settings.pct files and rename the namespace of the classes inside
  • CanvasFrame now redraws its Canvas after the user resizes the Frame
  • Added check to DC1394FrameGrabber so that a "Failed to initialize libdc1394" does not crash the JVM
  • FrameGrabber now selects the default grabber a bit better
  • Made sweeping changes (for the better, but still not finalized) to GNImageAligner, ProjectiveTransformer, ProjectiveGainBiasTransformer, and ProCamTransformer...
  • Fixed display issues with the mouse cursor on Windows, and made a few small cosmetic changes
  • Now tries harder to release native memory on time

July 30, 2010

  • Fixed crash that would occur in CanvasFrame for some video drivers
  • Fixed crash inside the code for direct alignment caused by the ROI getting set outside the image plane
  • Added deltaScale and tryToFixPlane settings to GNImageAligner (the first used as increment, randomly selected forward or backward, for finite difference), which sometimes help to jump over local minima

May 30, 2010

  • Fixed speed setting problem with the FlyCaptureFrameGrabber

April 16, 2010

  • Modified a few things to get better default behavior of gamma correction
  • Camera.triggerFlushSize now defaults to 5 (only affects OpenCVFrameGrabber and FFmpegFrameGrabber)
  • Replaced LMImageAligner by GNImageAligner, a more appropriate name for Gauss-Newton with lineSearch

April 8, 2010

  • Added support for OpenCV 2.1

April 5, 2010

  • Fixed mouse cursor under Windows when objectRoiAcquisition == USER
  • Added new VirtualBall visual element
  • Fixed up the Chronometer a bit
  • Added projectorVideoFile setting, whose images get merged with projectorImageFile

March 21, 2010

  • Initial release
