* Black Circle Detector
 
** Binary image
* Confusion Matrix Visualization
** Subpixel edge for gray scale images
** Fixed bug where a row/column was being lopped off
* Circular Asymmetric Grid Pattern
** Added labels
** For calibration
** Added ability to highlight one category
** As a general fiducial
** Added ability to query what's at a specific location
* Histogram of Oriented Gradient
* Local Image Normalization for use in machine learning
** Provided another implementation which is more faithful to original paper, but much slower
* Added weighted RGB to Gray conversion with example
** Can now independently configure block size along each axis
* Convolve
* VideoTrackerObjectQuadApp
** Better support for 64-bit float images
** Can now open webcams and videos
* Module "core" (formally "all") can be used to import everything in boofcv/main
** Improved UI
* Module "all" can be used to import everything in boofcv/main AND boofcv/integration
* Association
* Adjusted assisted calibration so that it's possible to provide a custom output directory
** Added helpful error messages when src and dst are not set
* Video
* Added support for F64 to F32 autocoding from regular F64 classes
** Xuggler's Maven repository has taken it down.  Effectively killing the zombie project
* 360 / Spherical camera support
** JavaCV has been integrated in as a replacement.
** Equirectangular image support
** Equirectangular to pinhole
** Equirectangular to cylinder
** Equirectangular rotate
* Dirty flag was not being set to false for cached image distort single band
* Changed minimum Java language level from 6 to 7
* Camera Model
** Renamed IntrinsicParameters to CameraPinhole
** Broke distortion off into a separate class which extends CameraPinhole
*** CameraPinholeRadial
** Added a new camera for wide FOV cameras: Universal Omnidirectional
** Created new transforms to handle non-pinhole cameras
* YAML
** Changed save format to YAML for camera model parameters.
** This should allow saved files to be independent of internal refactoring in BoofCV and cross platform, I hope.
* Deleted BoofAndroidFiles because you can now simply use yaml format
* Deep Learning
** Integrated in DeepBoof to provide support for deep artificial neural networks (ANN)
* Image Classification
** VGG trained on CIFAR10  (10 categories at 89.9%)
** Network-in-Network trained on ImageNet (1000 categories at 62.6%)
* FiducialDetector
** Takes in a distortion factory instead of camera parameters
** Added getIntrinsics()
** Added getImageLocation()
** Fixed bug where if a lens model with distortion was used then exchanged for one without the old distortion was not fully removed.
** Fixed bug where if intrinsic was not set it would still claim it could estimate the target's pose
* Binary Fiducial
** When decoding the image it now ignores border pixels of inner squares.  These tend to be very noisy.
** 7% improvement in regression test.  Idea taken from ArUco
* Commandline Fiducial Generator
** Can specify custom document size
* Added command line application for calibration fiducials
** Supports chessboard, square grid, square binary grid, circle asymmetric grid
* OpenCV Integration
** can read and write camera calibration for pinhole cameras with radial + tangential distortion
* FancyInterestPointRender
** Fixed addString() being a no-op.  Thanks R-Gerard for the bug report!
* Generate Square Fiducial Applications
** The post script format has been tweaked so that the page size is specified with the /PageSize command also
** A printing company was having issues correcting sizing the document until this change was made.
* Refactored FactoryCalibrationTarget -> FactoryFiducialCalibration
* FactoryMotion2D
** Removed image type specific functions and updated code for more recent API
* Fixed bug in StitchingFromMotion2D where reset() could cause a null pointer exception
* Android
** work around for a crash bug in Marshmallow
* Removed applet module in integration
* Template Matching
** Added correlation using FFT
** Tweaked API so that preprocessing of image can be performed
* TypeInterpolation renamed to InterpolationType for consistency
* Changed behavior of AssociateSurfBasic
** no longer throws an exception if src or dst features are empty
