v1.1.6

Release 1.1.6

v1.1.2

• Android
  • Better handling when the camera becomes inaccessible while it was reading it
• WorldToCameraToPixel
  • Supports homogenous coordinates
• BundleAdjustmentMetricResidualFunction
  • Fixed bug with homogeneous coordinates and rigid objects

v1.0.0: Release 1.0.0

• Version
  • Arbitrarily declared this as version 1.0.0
  • This was done to make version info more informative.
  • Originally it was decided that when face detection was added that would be 1.0 and that's still not on the menu
• Bundle Adjustment
  • Added a way to specify the camera state when a frame was captured
  • Added a new camera model that adjusts the focal length based on zoom factor
• Calibration
  • Tangental -> Tangential for consistency

v0.44

• SimulatePlanarWorld
  • Handles edge of objects better making motion appear smoother
• MicroQR
  • Rendering doesn't crash in special situations if you specify error level. Thanks for reporting Simon-Staal
  • You can ignore padding bytes now. Thanks for reporting Simon-Staal
• Demos
  • Added a color segmentation demo. Thanks Maxim Dossioukov.
• Android
  • Completely new build system that doesn't use any local files
  • New fragment camera code is available for use
  • Thanks Maxim Dossioukov for getting the first prototype of the build running
• Security
  • When de-serializing YAML it now uses Yaml(new SafeConstructor()) to prevent arbitrary code execution
  • Thanks Letian Yuan for the disclosure
  • SerializeFieldsYamlBase now has a whitelist of what can be deserialized
• Disparity
  • Fixed a catastrophic cancellation (CC) issue with floating point math with disparity score.
  • This CC issue effects SAD and NCC when dealing with distant objects.
  • Sub-pixel math is adjusted depending on type of error function. Improved SAD and CENSUS subpixel
  • Most application won't see a significant change in performance

v0.43.1: Release 0.43.1

- bug and "bug" fixes
- Updated dependencies

Release v0.43

Small release with a couple of minor breaking changes related to mesh

• ImageLinePruneMerge
  • Fixed type-o in near intersection formula. Thanks Erhan Erdemir for finding the problem.
• PointCloudIO
  • Added support for STL mesh files
• Added a mesh viewer
  • Swing panel, multiple controls, and help
  • Generic rendering engine

v0.41

Date : 2022/Sep/02
Version : 0.41

• Applications
  • Added Aztec Code generator
  • Removed unused flag to disable printing info in PDF documents
  • QR and other markers no longer require spacing between markers when there is only a single marker
  • Fixed units in manually specified document size
  • Create Calibration: Fixed units in manually specified paper size
  • Create Calibration: Fixed disable info flag
• Android
  • Properly handles multi camera systems by finding physical cameras inside a logical camera
• Demonstrations
  • Better Micro QR Code visualizations
• Contour Tracing
  • Can specify max and minimum contours using fractional size, i.e. ConfigLength instead of int
  • Added ability to specify maximum contour in places it was missing
  • ConfigPolygonFromContour doesn't produce identical results, but very similar
• ConvertBufferedImage
  • RGBA with pre-multiplied alpha will have channels swapped correctly
  • BufferedImage sub images work again, Thanks ConvertBufferedImage
• Added Aztec Code encoder and decoder
• QR Code
  • Fixed issue where it was rejecting version 1 QR codes at a highly skewed angle
  • Fixed issue where it failed to detect all QR when there was a cluster of several high version
  • If error correction passes it will stop processing the QR. Easier to diagnose issues.
• Micro QR Code
  • Doesn't keep on trying to decode a marker if it fails after the ECC check
• Various
  • Fixed crash in Niblack Family when output image was not resized to match input image
  • Image.setTo() now returns 'this' to enable chaining.
  • Can now colorize points based on camera reference frame, not just global
  • PlyCodec - writes correct header for little endian
• Stereo Disparity: Fixed bug where invalid values got cast to a byte when image was float, causing artifacts.
• RansacCalibrated now support concurrency
• Stereo
  • There's now the option to save the fit score for each pixel
• Photogrammetry
• Three-View Reconstruction: Does self calibration entirely inside of RANSAC
• Added ResolveThreeViewScaleAmbiguity
• N-View reconstruction code now directly uses the 3-view class and skips a projective scene step
• MultiBaselineDisparity now fuses into an inverse depth image
• 3D Mesh
  • Added related example code
  • Added support for saving mesh + color points to PLY
  • Added algorithms for converting stereo disparity into a 3D mesh
• Calibration
  • Mono and Stereo apps now generate calibration quality metrics for coverage and geometry
  • Mono and Stereo GUIs have option to show border and inner coverage
  • Added Division camera model
  • Added multi camera calibration
• ImageMiscOps
  • Added maskFill()
  • Added a generic filter()

v0.40.1
