JavaCV v0.4 Release Notes

Release Date: 2013-03-03 // about 11 years ago
    • Upgraded support to OpenCV 2.4.4
    • CanvasFrame.waitKey(-1) does not wait anymore and returns the last KeyEvent dispatched since the last call to it
    • Upgraded supported FFmpeg API to the 1.1 release branch
    • Fixed bug in FaceRecognition.java sample (issue #276)
    • Included Sobel(), Scharr(), Laplacian(), and Canny() from opencv_imgproc whose equivalent functions in the C API have missing parameters
    • Extended OpenKinectFrameGrabber with setDepthFormat() and setVideoFormat() methods to be able to set both formats independently (issue #273)
    • Fixed Blender.blend() having its @OutputMat incorrectly annotated as @InputMat (issue #272)
    • Added new RecordActivity.java Android sample from Shawn Van Every and Qianliang Zhang
    • Added missing allocate() methods for FunctionPointer in AVIOContext and others, which prevented these FFmpeg callbacks from functioning
    • Fixed infinite loop in FrameGrabber.Array.grab() (as used by ProCamCalib in the case of stereo cameras, issue #262) when FrameGrabber.getTimestamp() returns an invalid negative value (as with opencv_highgui) or when using different types of (unsynchronized) FrameGrabber together
    • Fixed cvQueryHistValue_1D() and other functions that use a raw CvArr object
    • Fixed problem when subclassing CanvasFrame
