• 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
  • 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.
