Change Log
Date    : 2016/12/07
Version : 0.26


Date Format: year/month/day
* Fixed a long standing unit test issue where convolve unit test would some times on some systems erratically fail
 
** Appears that sometimes the random numbers caused a buffer overflow for U8 images
---------------------------------------------
** Now why it didn't have the exact same numbers every time when it has a fixed seed is disturbing...
Date    : 2012/01/06
* Renamed EquirectangularTo* to *ToEquirectangular
Version : Alpha 0.4
** Those classes convert pixels in * coordinates into their location in the equirectangular image
 
** They are used to generate a * image from equirectangular
* Changed behavior of ConvertBufferedImage so that it won't automatically swap bands in MultiSpecitral image
* Float 32bit auto coding switched over to using auto64fto32f library
** orderBandsIntoRGB() has been provided to do that manually if needed
* TypeInterpolate is now InterpolationType for consistency
* All automatic convert to/from BGR and been removed from ConvertRaster
* Examples
* Fixed SURF related issue
** InterpolatePixel added
** Image bounds check was being incorrectly performed for integral image orientation estimation algorithms (Thanks Oleg Chernoguz for pointing this out)
** Image blur added
** FactoryOrientationAlgs.sliding_ii() was creating an average orienation alg for I32 images
** Non-Maximum Suppression added
** Some coordinates were integer instead of double
* Demonstrations
* Added comments to several factories and other classes
** Improved DemonstrationInterpolateScaleApp (renamed also)
* Added ant script for examples and readme.txt explaining how to use it
** Added DetectBlackEllipseApp
 
* Gradle
---------------------------------------------
** Will fail on dependency version conflict now
Date    : 2012/01/02
** Will fail when building release with SNAPSHOT dependencies
Version : Alpha 0.3
** Resolved xstream version conflict
 
* Updated DeepBoof
* Camera Calibration
** This is to get around an issue with a java wget library where it would hang instead of giving up
** Planar grid (Zhang 98)
** New code is also much more informative and prints out size info and download status\
** Camera calibration matrix from homographies
* Visualization
** Linear radial distortion
** Removed a bad +PI/2 from ellipse rendering.
** Decomposition of homography for calibration
* SnapToEllipseEdge * Fixed bug where it was only performing one iteration no matter what
** Nonlinear optimization of all parameters
* Circle Asymmetric Grid Target
* Calibration Grid Detection
** Fixed issue which was causing clusters not to form by not limiting number of neighbors within X distance
** Detects corners up to "pixel accuracy", in reality its probably worse than that
** When clustering ellipses orientation and major/minor axis size is now taken in account.
** Sub-pixel accuracy code exists but needs more work
** Significant net improvement in regression tests, only drop in performance in blurred images
* Added min and max values to ImageTestingOps.addGaussian()
* Tweaked factories related to wavelet denoising so that they take in an image type.
* Removed cyclical dependency between modules by creating a visualize modules
* Added to BinaryImageOps
** label to clusters
** clusters to binary
* Renamed ImageBase to ImageSingleBand
* Created a new ImageBase
* Flushed out MultSpectral image type more and extended ImageBase
** Created functions to convert to and from BufferedImage
* Changed behavior of several functions in GeneralizedImageOps to include MultiSpectral images
** refactor createImage -> createSingleBand
* Updated ant scripts
** Common template is now used for the different modules
** Fixed unit test and make it work across the whole project
* Added crop to ImageDistort
** If cropping is used the only part of the destimation image is processed
* Created calibration package to hold calibration related code
* Moved jars not part of the primary build into boofcv/lib/testing
* Started converting runtime benchmark code over to Caliper
** http://code.google.com/p/caliper/
 
---------------------------------------------
Date    : 2011/12/01
Version : Alpha 0.2
 
* Added integer polynomial interpolation
** Cleaned up polynomial interpolation code
* Fixed bug in PixelMath.bound() dealing with unsigned images
* Converting to a BufferedImage now marks it as modified
* Added min and max pixel values to ImageTypeInfo
* Added ComplexMath
* Added PolynomialSolver
* Added process(image) to PointSequentialTracker and renamed it to ImagePointTracker
* Added the following 3D vision code:
** Linear 8-point essential/fundamental matrix
** Linear 7-point essential/fundamental matrix
** Linear 4-point homography
** Extract camera motion from essential
** Extract camera and plane normal from homography
** Triangulate: Linear pixel depth
** Projective N Point (PNP): Linear N >= 6
* Added non-linear optimizer based upon Levenberg-Marquardt
* Added pixel region based descriptors
** Raw pixel values
** Normalized Cross Correlation (NCC)
* Added pixel region based trackers
* Added Sum of Absolute Difference (SAD) score for feature association with a few different descriptor types.
