OpenCV 1.1pre 版本的发布

时隔近两年，终于发布的OpenCV的第一个更新版本，看来原核心开发小组离开Intel，确实对OpenC
V的影响比较大。好在了解OpenCV的人越来越多，星星之火，可以燎原，信哉此言！

下面是 1.1pre 版本的更新LOG，仔细看了，内核没有太大的变动，应该还有不少BUG，估计大家会
很快把这些BUG抓出来。


Changes:
===================================================
            OpenCV 1.1pre1, October, 2008
===================================================

>>> New functionality/features: <<<

  - General:
    * Octave bindings have been added. See interfaces/swig/octave (for now, Linux only)
    * [Windows] OpenCV is now built with VS2005 with SSE2 and OpenMP support
      included (if you want to rebuild OpenCV using Express or
      Standard Edition of VS, use _make\opencv.vs2005.no_openmp.sln).
    * [Windows] Python bindings have been updated to use Python 2.6
    * [Windows] cvcam has been removed (as videoInput is now supported by highgui)

  - CXCORE, CV, CVAUX:
    * Speeded-up Robust Features (SURF), contributed by Liu Liu.
      see samples/c/find_obj.cpp and the documentation opencvref_cv.htm
    * Many improvements in camera calibration:
      - Added stereo camera calibration: cvStereoCalibrate, cvStereoRectify etc.
      - Single camera calibration now uses Levenberg-Marquardt method and supports
        extra flags to switch on/off optimization of individual camera parameters
      - The optional 3rd radial distortion parameter (k3*r^6) is now supported in
        every calibration-related function
    * 2 stereo correspondence algorithms:
      - very fast block matching method by Kurt Konolige
        (processes the Tsukuba stereo pair in <10ms on Core2Duo laptop)
      - slow but more accurate graph-cut based algorithm by Kolmogorov and Zabin
    * Better homography estimation algorithms (RANSAC and LMEDs)
    * new C++ template image classes contributed by Daniel Filip (Google inc.).
      see opencv/cxcore/include/cvwimage.h
    * Fast approximate nearest neighbor search (by Xavier Delacour)
    * Codebook method for background/foreground segmentation (by Gary Bradski)
    * Sort function (contributed by Shiqi Yu)
    * [OpenCV+IPP] Face Detection (cvHaarDetectObjects) now runs much faster
      (up to 2x faster) when using IPP 5.3 or higher.
    * Much faster (~4x faster) fixed-point variant of cvRemap has been added

  - MLL:
    * Python bindings for MLL have been added. There are no samples yet.

  - HighGUI:
    * [Windows, 32bit] Added support for videoInput library.
      Hence, cvcam is [almost] not needed anymore
    * [Windows, 32bit] FFMPEG can now be used for video decoding/encoding
      via ffopencv*.dll
    * [Linux] Added unicap support
    * Improved internal video capturing and video encoding APIs

  - Documentation:
    * OpenCV book has been published (sold separately :) see docs/index.htm)

  - New samples (opencv/samples):
    * Many Octave samples
    * find_obj.cpp (SURF), bgfg_codebook.cpp (Codebook BG/FG segmentation),
      stereo_calib.cpp (Stereo calibration and stereo correspondence)

>>> Bug fixes: <<<
     Many thanks to everybody who submitted bug reports and/or provided the patches!

    * added dma_unlisten to icvCloseCAM_DC1394 (thanks to Victor Benso)
    * LMEDs algorithm for cvFindFundamentalMat estimation has been fixed
    * Broken debug build of highgui in VS2005/2008 (SF #2056185, SF #1709435)
    * cvFindChessboardCorners memory leak and incorrect size checks
      (SF #1972896, SF #1910323)
    * disabling GTK causes v4l runtime error (SF #2088102)
    * cvsetmousecallback bug (SF #2053529)
    * libhighgui needed deprecated "img_convert" replacement (SF #2011753)
    * Segfault in createsamples caused by uninitialized variable (SF #1977989)
    * Data Alignment Issue in bgfg_gaussmix (SF #1961755)
    * libpng need to be updated (SF #1952793)
    * cvCreateVideoWriter_Win32 - identifier not found (SF #1944254)
    * Bug in cvmorph.cpp (SF #1908844)
    * dilate (cvDilate) works bogus with default kernel (SF #1887130)
    * CvEM non-default constructor declared but not defined (SF #1830346)
    * cvFloodFill (in ver 1.0) Hangs (SF #1790565)
    * double delete in CvImage (SF #1733437)
    * cvFilter2D anchor default value is not working properly (SF #1713779)
    * cvCvtColor - Bug? in converting HSV2RGB (SF #1676344)
    * Invalid selection of the MKL-dll version in cvUseOptimized() (SF #1633017)
    * ...

>>> Known issues:
    * Borland compiler is not supported (but might work) in this update.
    * 64-bit Windows is not supported (but might work) in this update.
    * SF bug tracker still contains over 50 records of open bugs.
      Many of them will be addressed in the next update.
