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    : 2011/12/01
* Renamed EquirectangularTo* to *ToEquirectangular
Version : Alpha 0.2
** Those classes convert pixels in * coordinates into their location in the equirectangular image
 
** They are used to generate a * image from equirectangular
* Added integer polynomial interpolation
* Float 32bit auto coding switched over to using auto64fto32f library
** Cleaned up polynomial interpolation code
* TypeInterpolate is now InterpolationType for consistency
* Fixed bug in PixelMath.bound() dealing with unsigned images
* Examples
* Converting to a BufferedImage now marks it as modified
** InterpolatePixel added
* Added min and max pixel values to ImageTypeInfo
** Image blur added
* Added ComplexMath
** Non-Maximum Suppression added
* Added PolynomialSolver
* Demonstrations
* Added process(image) to PointSequentialTracker and renamed it to ImagePointTracker
** Improved DemonstrationInterpolateScaleApp (renamed also)
* Added the following 3D vision code:
** Added DetectBlackEllipseApp
** Linear 8-point essential/fundamental matrix
* Gradle
** Linear 7-point essential/fundamental matrix
** Will fail on dependency version conflict now
** Linear 4-point homography
** Will fail when building release with SNAPSHOT dependencies
** Extract camera motion from essential
** Resolved xstream version conflict
** Extract camera and plane normal from homography
* Updated DeepBoof
** Triangulate: Linear pixel depth
** This is to get around an issue with a java wget library where it would hang instead of giving up
** Projective N Point (PNP): Linear N >= 6
** New code is also much more informative and prints out size info and download status\
* Added non-linear optimizer based upon Levenberg-Marquardt
* Visualization
* Added pixel region based descriptors
** Removed a bad +PI/2 from ellipse rendering.
** Raw pixel values
* SnapToEllipseEdge * Fixed bug where it was only performing one iteration no matter what
** Normalized Cross Correlation (NCC)
* Circle Asymmetric Grid Target
* Added pixel region based trackers
** Fixed issue which was causing clusters not to form by not limiting number of neighbors within X distance
* Added Sum of Absolute Difference (SAD) score for feature association with a few different descriptor types.
** 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
---------------------------------------------
