Version : 0.23
* 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
* Refactored image data structure names for consistency and brevity
** Now why it didn't have the exact same numbers every time when it has a fixed seed is disturbing...
** Sorry for the massive refactoring
* Renamed EquirectangularTo* to *ToEquirectangular
** ImageUInt8 -> GrayU8
** Those classes convert pixels in * coordinates into their location in the equirectangular image
** MultiSpectral -> Planar
** They are used to generate a * image from equirectangular
** Interleaved is unchanged
* Float 32bit auto coding switched over to using auto64fto32f library
* Removed Alpha from version name since it was pointless and non-informative
* TypeInterpolate is now InterpolationType for consistency
** Will hit 1.0 once a (good) face detector is added
* Examples
* Updated dense descriptor configurations to include a default sampling period
** InterpolatePixel added
** SIFT, Fast SURF, Stable SURF
** Image blur added
* FactoryDescribeImageDense
** Non-Maximum Suppression added
** Now accepts null for configuration and creates a default
* Demonstrations
* FactoryOrientation
** Improved DemonstrationInterpolateScaleApp (renamed also)
** SIFT now accepts a null argument.  Thanks pcmoen for pointing out this bug.
** Added DetectBlackEllipseApp
* ImplOrientationImageAverageIntegral
* Gradle
** Fixed internal null pointer exception
** Will fail on dependency version conflict now
** Fixed bad unit test
** Will fail when building release with SNAPSHOT dependencies
** Thanks pcmoen for pointing out this bug
** Resolved xstream version conflict
* Hamming Distance
* Updated DeepBoof
** New algorithm from Sean Eron Anderson Bit Twiddling Hack
** This is to get around an issue with a java wget library where it would hang instead of giving up
** 68 times faster than equivalent older code
** New code is also much more informative and prints out size info and download status\
** 8 times faster than a lookup table!
* Visualization
** Thanks pcmoen for finding this gem and the pull request
** Removed a bad +PI/2 from ellipse rendering.
* FactoryDerivative
* SnapToEllipseEdge * Fixed bug where it was only performing one iteration no matter what
** Deleted type-specific functions
* Circle Asymmetric Grid Target
* BorderType.VALUE is now ZERO because it always defaulted to zero
** Fixed issue which was causing clusters not to form by not limiting number of neighbors within X distance
** When clustering ellipses orientation and major/minor axis size is now taken in account.
** Significant net improvement in regression tests, only drop in performance in blurred images
