+<h2>2.0</h2>
+<p class="Blurb"><i>(September, 2009)</i></p>
+
+<pre>
+>>> New functionality, features:
+
+ - General:
+ * Installation package on Windows has been fixed,
+ MinGW is used for precompiled binaries
+ (see the release notes on the SourceForge site)
+
+ * autotools-based build has been repaired
+
+ - MLL:
+ * The new-style class aliases (e.g. cv::SVM ~ CvSVM) and the train/predict methods,
+ taking cv::Mat in addition to CvMat, have been added. So now MLL can be used
+ more seamlesly with the rest of the restyled OpenCV.
+
+>>> Bug fixes:
+
+ - A _lot_ of bugs present in 2.0 beta have been fixed, see the OpenCV bug tracker
+ http://sourceforge.net/tracker/?group_id=22870&atid=376677
+ Thanks to everybody who submitted bug reports and/or patches!

+
+<hr><h2>2.0 beta</h2>
+<p class="Blurb"><i>(September, 2009)</i></p>
+
+<pre>
+>>> New functionality, features: <<<
+
+ - General:
+ * The brand-new C++ interface for most of OpenCV functionality
+ (cxcore, cv, highgui) has been introduced.
+ Generally it means that you will need to do less coding to achieve the same results;
+ it brings automatic memory management and many other advantages.
+ See the C++ Reference section in opencv/doc/opencv.pdf and opencv/include/opencv/*.hpp.
+ The previous interface is retained and still supported.
+
+ * The source directory structure has been reogranized; now all the external headers are placed
+ in the single directory on all platforms.
+
+ * The primary build system is CMake, http://www.cmake.org (2.6.x is the preferable version).
+ + In Windows package the project files for Visual Studio, makefiles for MSVC,
+ Borland C++ or MinGW are note supplied anymore; please, generate them using CMake.
+
+ + In MacOSX the users can generate project files for Xcode.
+
+ + In Linux and any other platform the users can generate project files for
+ cross-platform IDEs, such as Eclipse or Code Blocks,
+ or makefiles for building OpenCV from a command line.
+
+ * OpenCV repository has been converted to Subversion, hosted at SourceForge:
+ http://opencvlibrary.svn.sourceforge.net/svnroot/opencvlibrary
+ where the very latest snapshot is at
+ http://opencvlibrary.svn.sourceforge.net/svnroot/opencvlibrary/trunk,
+ and the more or less stable version can be found at
+ http://opencvlibrary.svn.sourceforge.net/svnroot/opencvlibrary/tags/latest_tested_snapshot
+
+ - CXCORE, CV, CVAUX:
+
+ * CXCORE now uses Lapack (CLapack 3.1.1.1 in OpenCV 2.0) in its various linear algebra functions
+ (such as solve, invert, SVD, determinant, eigen etc.) and the corresponding old-style functions
+ (cvSolve, cvInvert etc.)
+
+ * Lots of new feature and object detectors and descriptors have been added
+ (there is no documentation on them yet), see cv.hpp and cvaux.hpp:
+
+ + FAST - the fast corner detector, submitted by Edward Rosten
+
+ + MSER - maximally stable extremal regions, submitted by Liu Liu
+
+ + LDetector - fast circle-based feature detector by V. Lepetit (a.k.a. YAPE)
+
+ + Fern-based point classifier and the planar object detector -
+ based on the works by M. Ozuysal and V. Lepetit
+
+ + One-way descriptor - a powerful PCA-based feature descriptor,
+ (S. Hinterstoisser, O. Kutter, N. Navab, P. Fua, and V. Lepetit,
+ "Real-Time Learning of Accurate Patch Rectification").
+ Contributed by Victor Eruhimov
+
+ + Spin Images 3D feature descriptor - based on the A. Johnson PhD thesis;
+ implemented by Anatoly Baksheev
+
+ + Self-similarity features - contributed by Rainer Leinhart
+
+ + HOG people and object detector - the reimplementation of Navneet Dalal framework
+ (http://pascal.inrialpes.fr/soft/olt/). Currently, only the detection part is ported,
+ but it is fully compatible with the original training code.
+ See cvaux.hpp and opencv/samples/c/peopledetect.cpp.
+
+ + Extended variant of the Haar feature-based object detector - implemented by Maria Dimashova.
+ It now supports Haar features and LBPs (local binary patterns);
+ other features can be more or less easily added
+
+ + Adaptive skin detector and the fuzzy meanshift tracker - contributed by Farhad Dadgostar,
+ see cvaux.hpp and opencv/samples/c/adaptiveskindetector.cpp
+
+ * The new traincascade application complementing the new-style HAAR+LBP object detector has been added.
+ See opencv/apps/traincascade.
+
+ * The powerful library for approximate nearest neighbor search FLANN by Marius Muja
+ is now shipped with OpenCV, and the OpenCV-style interface to the library
+ is included into cxcore. See cxcore.hpp and opencv/samples/c/find_obj.cpp
+
+ * The bundle adjustment engine has been contributed by PhaseSpace; see cvaux.hpp
+
+ * Added dense optical flow estimation function (based on the paper
+ "Two-Frame Motion Estimation Based on Polynomial Expansion" by G. Farnerback).
+ See cv::calcOpticalFlowFarneback and the C++ documentation
+
+ * Image warping operations (resize, remap, warpAffine, warpPerspective)
+ now all support bicubic and Lanczos interpolation.
+
+ * Most of the new linear and non-linear filtering operations (filter2D, sepFilter2D, erode, dilate ...)
+ support arbitrary border modes and can use the valid image pixels outside of the ROI
+ (i.e. the ROIs are not "isolated" anymore), see the C++ documentation.
+
+ * The data can now be saved to and loaded from GZIP-compressed XML/YML files, e.g.:
+ cvSave("a.xml.gz", my_huge_matrix);
+
+ - MLL:
+ * Added the Extremely Random Trees that train super-fast,
+ comparing to Boosting or Random Trees (by Maria Dimashova).
+
+ * The decision tree engine and based on it classes
+ (Decision Tree itself, Boost, Random Trees)
+ have been reworked and now:
+ + they consume much less memory (up to 200% savings)
+ + the training can be run in multiple threads (when OpenCV is built with OpenMP support)
+ + the boosting classification on numerical variables is especially
+ fast because of the specialized low-overhead branch.
+
+ * mltest has been added. While far from being complete,
+ it contains correctness tests for some of the MLL classes.
+
+ - HighGUI:
+ * [Linux] The support for stereo cameras (currently Videre only) has been added.
+ There is now uniform interface for capturing video from two-, three- ... n-head cameras.
+
+ * Images can now be compressed to or decompressed from buffers in the memory,
+ see the C++ HighGUI reference manual
+
+ - Documentation:
+ * The reference manual has been converted from HTML to LaTeX (by James Bowman and Caroline Pantofaru),
+ so there is now:
+ + opencv.pdf for reading offline
+ + and the online up-to-date documentation
+ (as the result of LaTeX->Sphinx->HTML conversion) available at
+ http://opencv.willowgarage.com/documentation/index.html
+
+ - Samples, misc.:
+ * Better eye detector has been contributed by Shiqi Yu,
+ see opencv/data/haarcascades/*[lefteye|righteye]*.xml
+ * sample LBP cascade for the frontal face detection
+ has been created by Maria Dimashova,
+ see opencv/data/lbpcascades/lbpcascade_frontalface.xml
+ * Several high-quality body parts and facial feature detectors
+ have been contributed by Modesto Castrillon-Santana,
+ see opencv/data/haarcascades/haarcascade_mcs*.xml
+
+>>> Optimization:
+ * Many of the basic functions and the image processing operations
+ (like arithmetic operations, geometric image transformations, filtering etc.)
+ have got SSE2 optimization, so they are several times faster.
+
+ - The model of IPP support has been changed. Now IPP is supposed to be
+ detected by CMake at the configuration stage and linked against OpenCV.
+ (In the beta it is not implemented yet though).
+
+ * PNG encoder performance improved by factor of 4 by tuning the parameters
+
+>>> Bug fixes: <<<
+ TBD
+ (see http://sourceforge.net/tracker/?group_id=22870&atid=376677 of the list
+ of the closed and still opened bugs).
+
+ Many thanks to everybody who submitted bug reports and/or provided the patches!
+
+>>> Known issues:
+ * configure+autotools based build is currently broken.
+ Please, use CMake.
+ * OpenCV bug tracker at SF still lists about 150 open bugs.
+ Some of them may be actually fixed already, and most of the remaining bugs
+ are going to be fixed by OpenCV 2.0 gold.
+ * IPP is not supported. As the new OpenCV includes a lot of SSE2 code,
+ it may be not such a serious problem, though.
+ The support (at least for most important functions that do not have
+ SSE2 optimization) will be returned in 2.0 gold.
+ * The documentation has been updated and improved a lot, but it still
+ needs quite a bit of work:
+ - some of the new functionality in cvaux is not described yet.
+ - the bibliography part is broken
+ - there are quite a few known bugs and typos there
+ - many of the hyperlinks are not working.
+ * The existing tests partly cover the new functionality
+ (via the old backward-compatibility OpenCV 1.x API), but the coverage is
+ not sufficient of course.
+ * The new-style Python interface is not included yet
+
+ Many of the problems will be addressed in 2.0 gold.
+ If you have found some specific problem, please, put the record to the bug tracker:
+ http://sourceforge.net/tracker/?group_id=22870
+ Better if the bug reports will include a small code sample in C++/python +
+ all the necessary data files needed to reproduce the problem.
