Date  : 2015/11/09 Version : Alpha 0.20

• Improved pose stability of calibration targets as fiducials
  • Turns out they were using a linear estimate only
  • Now uses EPnP followed by a few steps of non-linear refinement
• PerspectiveOps.createIntrinsic() which creates intrinsic parameters from a known FOV and image shape
• New WebcamInterface and some examples now can run on your webcam
  • Requires WebcamCapture
• ExamplePointFeatureTracker has colorized points to make it easier to identify the same point
• Polygon Detector
  • Simplified code by removing requirement the CW/CCW must be known by helper classes
• BinaryPolygonConvexDetector
  • Much improved performance on non-square like shapes
  • Stability is much better on very small shapes
• Merged data/applet and data/evaluation together
  • Renamed to data/examples
• Renamed package boofcv/evaluations to boofcv/demonstrations
  • It no longer served as a place for benchmarks
• VisualizeBinaryData
  • Marked buffered image as dirty when rendering a labeled image
• Removed Processing from project
  • Might spawn into its own project if there is more interest in the future
• Binary Thresholding
  • Created a generic config class which supports all current types
• Square Fiducial Generator App
  • no longer defaults to a page border of 1cm
  • page border is actually user configurable
  • border and white border are correctly handled
• Square Binary Fiducial
  • Can now handle grids with arbtirary widths!
    • Thanks Nathan Pahucki npahucki@gmail.com for submitting this pull request
  • The width of the border can now be adjusted too
• Moved PyBoof to it's own repository at https://github.com/lessthanoptimal/PyBoof
  • It will be update on its own cycle
• Chessboard Detector
  • Improved stability especially for slightly blurred images
• PointTrackerKltPyramid
  • Fixed uninitialized variable in one of the constructors. Thanks ericbhatti
  • Change it from two constructors down to one constructor
• Created built in class for removing perspective distortion
  • RemovePerspectiveDistortion
• Partially observable calibration targets are now supported
  • Mathematically at least. Targets which can be partially observed are not supported yet
• ConvertBufferedImage.stripAlphaChannel()
  • Can be used to ensure that an alpha channel is not in the buffered image
  • Inspired by an issue pete-experimenter had
• Renamed FiducialDetector to FiducialPoseDetector
  • Done to accommodate fiducials in which you don't care about the pose
• Morphological Thinning has been fixed and tweaked
  • Thanks Emil Hellman who first pointed out the issue and helped solve/improve the implementation
• Locally adaptive threshold techniques that had a bias term now have a scale term.
  • Much more useful since bias was intensity and value range dependent
