BoofCV Change Log

Date  : 2016/12/01 Version : 0.25

• Black Circle Detector
  • Binary image
  • Subpixel edge for gray scale images
• Circular Asymmetric Grid Pattern
  • For calibration
  • As a general fiducial
• Histogram of Oriented Gradient
  • Provided another implementation which is more faithful to original paper, but much slower
  • Can now independently configure block size along each axis
• VideoTrackerObjectQuadApp
  • Can now open webcams and videos
  • Improved UI
• Association
  • Added helpful error messages when src and dst are not set
• Added support for F64 to F32 autocoding from regular F64 classes
• 360 / Spherical camera support
  • 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
