Change Log
Date Format: year/month/day
Date : 2012/02/01 Version : Alpha 0.5
- Improved SURF performance
- Fixed various bugs and changed algorithm to improve performance
- Both speed and stibility have been improved
- Now is the best performing SURF implementation in the benchmark
- Fixed various bugs and changed algorithm to improve performance
- ImplOrientationSlidingWindowIntegral has been replaced with a faster and more accurate algorithm
- Improved integral image support
- Improved sparse gradient support
- Refactored sparse image operator code
- Added SparseImageSample interface
- Added/Improved unconstrained non-linear optimization code
- Quasi-Newton line search
- Levenberg-Marquardt
- Geometric vision and calibration code which uses non-linear optimization now works correectly
- Started converting internal micro benchmarks to use Caliper
Date : 2012/01/06 Version : Alpha 0.4
- Changed behavior of ConvertBufferedImage so that it won't automatically swap bands in MultiSpecitral image
- orderBandsIntoRGB() has been provided to do that manually if needed
- All automatic convert to/from BGR and been removed from ConvertRaster
- Fixed SURF related issue
- Image bounds check was being incorrectly performed for integral image orientation estimation algorithms (Thanks Oleg Chernoguz for pointing this out)
- FactoryOrientationAlgs.sliding_ii() was creating an average orienation alg for I32 images
- Some coordinates were integer instead of double
- Added comments to several factories and other classes
- Added ant script for examples and readme.txt explaining how to use it
Date : 2012/01/02 Version : Alpha 0.3
- Camera Calibration
- Planar grid (Zhang 98)
- Camera calibration matrix from homographies
- Linear radial distortion
- Decomposition of homography for calibration
- Nonlinear optimization of all parameters
- Calibration Grid Detection
- Detects corners up to "pixel accuracy", in reality its probably worse than that
- Sub-pixel accuracy code exists but needs more work
- 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
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.
Date : 2011/11/01 Version : Alpha 0.1
- Initial public release
