-=============================================================================
- OpenCV 1.0 RC1, August 11, 2006
-=============================================================================
-
->>> New functionality/features: <<<
- - New Compilers/Environments supported:
- * GCC 4.x
- * Visual Studio .NET 2005.
- Note that: a) Project files .vcproj's and the corresponding solution files
- have been converted to VS.NET 2005 format, thus they can not
- be opened with VS.NET 2003. As a workaround, one may convert
- project files and workspaces for Visual Studio 6.0 to VS.NET 2003.
- b) The projects can be built for Win32 and x64 (a.k.a. EM64T/AMD64) platforms.
- c) OpenMP support is turned on by default.
- * On MacOSX universal OpenCV binaries are now built by default, so both
- PPC and Intel Mac's are fully supported.
- * Borland C++ support has been removed. There is still script
- utils\gen_make.py available that can generate makefile.bcc's out of
- MSVC's project files (not tested with rc1).
- * New command-line makefiles _make\makefile.* are introduced that allow user
- to build OpenCV for Win64 (EM64T/AMD64 and Itanium). For details, see INSTALL file.
-
- - cxcore:
- * added several new functions:
- cvMixChannels, cvRandShuffle, cvRange, cvCalcPCA, cvProjectPCA, cvBackProjectPCA,
- cvNormalize, cvReduce, cvGetNumThreads, cvSetNumThreads, cvGetThreadNum.
- See docs/ref/opencvref_cxcore.htm for details.
- * extended cvCalcCovarMatrix, cvMulTransposed
- * added macros for the library version: see cxcore/include/cvver.h
- * added C++ classes CvImage and CvMatrix:
- see cxcore/include/cxcore.hpp and the sample samples/c/image.cpp
- * the maximum number of channels in matrices has been increased up to 64.
- though, only the basic functions can handle such images.
- - cv:
- * new functions:
- cvPyrMeanShiftFiltering, cvWatershed, cvGetAffineTransform.
- see docs/ref/opencvref_cv.htm for details.
- * extended:
- cvDistTransform (true distance transform algorithm),
- cvThresh (Otsu adaptive algorithm),
- cvCanny (using true gradient as an option)
- * all the filtering functionality has been reworked,
- new C++ classes for linear separable and non-separable filtering,
- morphology, laplace, box filer (blur) have been added.
- see cv/include/cv.hpp.
- The older C API is still supported and is preferrable sometimes
- (e.g. when IPP is used).
- ****** API changes:
- * cvCamShift, cvBoxPoints and all the other functions
- taking/returning an angle (as a field of the structure CvBox2D
- or as a standalone parameter) now measure the angles in degrees.
-
- - cvaux:
- * new large video surveillance module has been added
- (cvaux/src/vs and cvaux/include/cvvidsurv.h).
- It implements smart blob tracking. See the description at docs/vidsurv)
- - ml (stands for Machine Learining):
- * this is a completely new C++ module containing classes for statistical
- classification, regression and clustering. See docs/ref/opencvref_ml.htm.
- - highgui:
- * the whole video capturing code has been restructured and split by modules,
- better function names have been introduced (older names are supported via macros)
- * Quicktime (MacOSX) and Xine (Linux, (attention: watch the license!)) support added.
- * many small and big improvements have been made
- in most of the video capturing modules
- * a helper thread can be used to refresh highgui windows content w/o having to
- call cvWaitKey() (Linux only).
-
- - Bindings/interfaces:
- * IPP 5.1.* is now supported and this is a recommended version of IPP
- to use with OpenCV. One may build custom IPP DLL for easier binary
- redistribution (see interfaces/ipp)
- * Python bindings have been greatly improved and extended
- (see interfaces/swig[/python] and samples/python).
-
->>> Optimizations: <<<
- - The following filtering functions have been significantly optimized
- using the new IPP 5.1 functionality:
- cvSobel, cvLaplace, cvErode, cvDilate.
- - cvFilter2D now runs much faster with larger kernels (using DFT-based method)
- - Several functions have been parallelized with OpenMP:
- cvHaarDetectObjects, cvCalcOpticalFlowPyrLK, cvDistTransform (the new algorithm only),
- so they should run ~50-80% faster on dual core CPUs, when the code is built
- with Intel compiler or MSVC2005 (as the precompiled OpenCV binaries are).
-
->>> Bug fixes: <<<
-
- - A lot of bugs have been fixed. We would like to thank all the people
- who submitted bug reports and/or patches.
- This is incomplete list of the bugs fixed.

-=============================================================================
- OpenCV beta 4, Friday, August 13, 2004
-=============================================================================
-
->>> Global changes: <<<
- - cv library has been split into
- cv (image processing and computer vision part)
- and cxcore (basic functionality that is shared with OpenPNL)
-
- so any application that was linked with cv should now be linked with both cv and cxcore.
-
- - DLLs now have a version number (096 for beta 4) in their names, so they do not
- conflict with applications using libraries from previous (and future) OpenCV releases.
- Import libraries on Windows do not have version numbers in their names.
-
- - Many of applications have been dropped/replaced with simple demo samples (see opencv/samples/c):
- - Hawk, HMMDemo, VMDemo and vmdemotk have been dropped completely.
- - LKDemo and cvlkdemo have been replaced with sample lkdemo.c
- - HaarFaceDetect has been replaced with facedetect.c
- - CamShiftDemo and cvcsdemo have been replaced with camshiftdemo.c
-
- - Some of obsolete functions, including e-HMMs, eigen objects, view morphing ...
- have been moved from cv to cvaux.
-
- - A lot of external dependencies have been removed together
- with corresponding demo applications: TCL/TK, FLTK, Motif, MFC
-
- - Pre-built binaries in windows distribution are now built using Intel Compiler 8.x
- resulting in noticeable performance increase for many functions.
-
- - On linux there is no cvcam anymore. Highgui should be used instead
- Windows version of cvcam is also obsolete and will be removed as soon
- as DirectShow support will be added to highgui.
-
- - Interfaces for EiC, Ch and MATLAB have been temporarily dropped.
-
->>> New features/functionality: <<<
-
- - Support for Miscrosoft Visual Studio .NET 2003 (see ../_make/*.sln) and
- Borland C++ BuilderX (see ../_make/cbuilderx/*.bpgr) has been added.
-
- - More functions from IPP 4.x are supported.
-
- - Support for 16u (16-bit unsigned) type has been added.
-
- - New functions for arbitrary convolution (cvFilter2D),
- geometrical transformations (cvWarpAffine, cvWarpPerspective) have been added.
- Another 2 interpolation methods have been added to cvResize.
-
- - XML input/output has been completely rewritten. Now arbitrarily
- complex structures may be easily read and very easily written to XML.
- In parallel, YAML (www.yaml.org) is supported.
-
- - Haar object detection:
- - the code has been transferred to cv
- - trained classifiers are now stored in XML/YAML format
- (there is still possibility to load classifiers from directories).
- - support for classifiers trees, rather than cascades has been added
- (see opencv/apps/haartraining/)
- - more cascades for detecting frontal face, new cascades for detecting
- profile face and body have been added (thanks to David Bradley,
- Hannes Kruppa and Bernt Schiele). see opencv/data/readme.txt for details.
- - classifier for detecting frontal face has been removed from the code.
-
- - Reference manual has been reorganized and it is now covers entire cxcore, cv
- and highgui libraries.
-
- - New object-oriented test engine has been created. cxcore functionality
- has been tested using it (see opencv/bin/cxcoretest.exe,
- opencv/tests/{cxts;cxcore/src})
-
- - All the drawing functions now support antialiasing and multi-channel images
- of arbitrary depth (earlier only single-channel images of depth>8bit were supported).
- Floodfill also supports color floating-point images now.
-
- - Linux version of highgui now supports capturing video from cameras via
- dc1394 and/or V4L2 (thanks to Magnus Lundin for the patch) (not tested!)
-
- - Linux version of highgui now uses GTK+ 2.x instead of Motif.
-
- - Several patches by Premnath Dubey have been applied to Windows version of cvcam.
- It is now possible to set the camera resolution from within a program.
-
->>> Optimizations: <<<
-
- - DFT functions now use mixed-radix algorithm and, optionally,
- DFT/FFT functions from IPP.
-
- - Now matrix multiplication is done by blocks resulting
- in better cache utilization => better performance.
- Optionally, gemm from Intel MKL can be used.
-
- - Lucas-Kanade Optical flow includes a few heuristics that significantly
- improve performance (thanks to Alexander Kibkalo for the patch).
-
- - cvRound now uses inline assembly when built with Visual C++, Intel Compiler
- or GCC 3.x (the latter is done via C99 lrint() function). That also
- resolves the problem with Direct3D and few others (thanks to HCK (hengck23) for the hint).
-
- - Morphology with arbitrary-shaped element now processes only
- the neighbors corresponding to non-zero coefficients (so cvFilter2D does)
- in a single loop that gives +1.5x performance increase.
-
- - alloca() has been replaced by cvStackAlloc that returns an aligned pointer.
- For some functions it improved performance a lot.
-
- - Arithmetic operations with mask are now done using non-mask operations +
- copy with mask. It helps to engage IPP for such operations and is in general faster.
-
- - cvSeqSort and generic sorting macro (CV_IMPLEMENT_QSORT...) now use Berkeley qsort
- that almost eliminates the worst (quadratic complexity) case and
- improves performance on nearly-sorted sequences.
-
- - Some typical operations on data structures, such as retrieving sequence element,
- retrieving graph edge, positioning sequence reader have been optimized for
- faster average performance and smaller overhead.
-
- - Special vectorized versions of double-precision math functions (cvExp, cvLog etc.)
- have been created. Optionally, ippvm from IPP is used when available,
- which gives incredible performance improvement.

- 32-bit Linux versions with specially patched kernels)
- as long as their linear sizes still fit into 0..INT_MAX.
- - Another boosting base for frontal face detection (Gentle Adaboost 20x20) added:
- opencv\apps\HaarFaceDetect\Frontal-GAB-20x20.zip. Uncompress it somewhere and

-
-=============================================================================
- Release OpenCV beta 2.1, Friday, November 30, 2001
-=============================================================================
-
->>> New features/functionality: <<<
-
- - IPL is not required nor by OpenCV neither by demos anymore
- (even under Win32 and even in default configuration).
- Tests still need it. To get into full IPL-compatibility mode, call
- CV_TURN_ON_IPL_COMPABILITY() on your program startup. It is needed only if
- the code mix OpenCV/IPL image allocation/deallocation functions.
-
- - Makefiles to build cv, cvaux and highgui libraries with Visual C++ 6.0,
- Borland C++ 5.5 (free), Intel C++ Compiler 5.0 and Mingw GNU C++ 2.95.3 added.
- - Arithmetic and logical operations (w/o mask support) were optimized using
- MMX and SSE instructions.
- - Positions of depth and numchannels flags in CvMat "type" field were exchanged.
- Now CV_8U == CV_8UC1, CV_32F == CV_32FC1 etc.
- - Definition of rows/height and cols/width fields of CvMat was changed to provide
- C -> C++ code compatibility.
- - Non-planar objects support added into cvFindExtrinsicParams
- - A few more color transforms bgr/rgb <-> gray added.
- - New function cvRand for filling CvMat/IplImage with uniformly distributed
- random numbers added
- - New function cvResize for image zooming/shrinking with nearest-neigbor
- or bilinear interpolation was added
- - Texture descriptors calculation was added to cvaux library.
- - Faster image segmentation was added to cvaux library
- - new ippcv binaries included (previous release contained somewhat outdated binaries).
- - calibration filter uses batch-mode undistortion now (cvUnDistortInit + cvUnDistort)
- - C++ calibration + stereo rectification class was added to cvaux.
-
->>> Here is the list of fixed bugs: <<<
-
- - 3x3 matrix inversion was incorrect
- - minmaxloc returned wrong extrema positions in case of
- continuous input arrays (i.e. w/o gaps between subsequent rows)
- - arithmetic operations cvAddS and cvSub[R]S produce wrong result on small
- input arguments
- - the package could not be built with gcc 2.96 under linux
- - cvFillImage function was missed
- - cvRound, cvFloor and cvCeil functions worked incorrectly
- when 80-bit internal precision was set (it is a default mode under Linux).
- Also, the function were slightly inaccurate even with 64-bit internal precision set.
- - cvRound, cvFloor, cvCeil and cvSetIdentity functions worked incorrectly at
- big-endian processors (i.e. on processors, where the most significant byte goes first)
- - Several pieces in the library were not portable to 64-bit processors
- - cvFindChessBoardCornerGuesses could not find chess board in some particular cases.
- The current solution is just some workaround and playing with thresholds.
- Better method is ahead.
-
-The following problems still exist:
-======================================
-1. FitEllipse doesn't work properly when input points are almost on the single line.
- In alpha 3.4 it output infinite values. In this release it outputs all zeros.
-
-2. FindFundamentalMatrix - the same. Inaccurate result in some cases.
-
-
-=============================================================================
- Release OpenCV beta 2, Friday, August 14, 2001
-=============================================================================
-
- 1. CvMat structure can be used passed to almost any function that accepts IplImages
- and vice versa. It is done via introduction of dummy type CvArr which is synonym
- for void*.
- 2. The following basic matrix/image operations were added:
- arithmetics (+,-,*)
- logic (and,or,xor)
- helper operations (copy,set,mirror)
- color transforms
-
- arithmetics (+,-) and logic operations accept mask as an optional parameter
-
- 3. The library reference manual has been restructurized. Now all the material is
- divided into programmer guide and function reference. Each of these parts
- is split into 6-7 major areas, covered by the library.
-
- 4. Image statistics, background accumulation and some other function groups
- extended to handle wider sets of images/matrices formats.
-
- 5. Mask support added to cvGoodFeaturesToTrack
-
- 6. Drawing functions can now be used with floating-point images and extended
- with 4-connectivity variants (connectivity is passed as an optional parameter).
- cvDrawContours accept negative maximal level value, which means draw (or paint)
- the passed contour and all its children up to abs(max_level) level, so
- hack with clearing h_next field during connected components labeling is not
- need any more.
-
- 7. cvSVD improved. It can now handle both m >= n and m < n cases and it is faster
- than the previous variant. cvPseudoInv function is added that calculates
- pseudo-inverse for given matrix (Only m >= n is handled properly right now).
-
- 8. cvSeqPush[Front] and cvSeqInsert return pointer to the inserted element.
-
- 9. More experimental stuff has been added (including graph traversal functions,
- etc). It resides in the separate library CvAux
-
- 10. Morphology functions speeded up (arbitrary structuring element case).
