operations on regions enclosed by contours or polygons.
Bar Code and Data Code Reading
HALCON now provides a new bar code reader, which robustly finds any potential bar code region, can read multiple codes at the same time, and is easy to use. Furthermore, the bar code reader can now read RSS-14, RSS-14 Truncated, RSS Limited, and RSS Expanded bar code symbols.
HALCON’s 2D data code reader now allows to assess the print quality, compliant with the international standard ISO/IEC 15415.
Other New Operators and Extensions
Contours can now also be read from and written to DXF files.
HALCON now provides operators to grab images (or image tuples), regions, and control data.
HALCON now provides a new operator for image inpainting based on coherence transport.
The generation of mosaics (image stitching) has been enhanced by new operators and extensions of existing ones.
HALCON now provides operators to create and interactively draw and modify XLD contours that approximate NURBS curves.
HALCON now provides new operators to compute the dense optical flow vector field between two images.
HALCON now provides operators for computing the polar transformation of regions and XLDs.
HALCON now provides operators for computing the transformation matrix for a principal component transformation of a multi-channel image and for applying an arbitrary linear gray value transformation.
HALCON now provides operators for powerful string processing based on regular expressions.
HALCON now provides an operator for testing whether a region is a subset of another region.
HALCON’s variation model has been extended with three new operators and various enhancements of the existing operators.
Speed-Up
HALCON in general is now significantly faster because of a faster memory management.
A new operator allows to smooth images with the extremely fast binomial filter. This filter is also available via other filter operators.
In addition, many operators have been sped up significantly, e.g., laplace, compare_variation_model, edges_image and edges_sub_pix, fit_ellipse_contour_xld and fit_circle_contour_xld, and sobel_amp.
HDevelop
Complete Revision of the User Interface
HDevelop’s Graphical User Interface has been completely revised to improve usability. Besides design improvements like new icons, many functional extensions have been introduced in almost every part of HDevelop. Due to their number, the list of detailed changes contains only the most important ones. The completely revised HDevelop User’s Guide contains a detailed description of the current functionality.
Assistants
HDevelop now provides assistants that simplify the use of important machine vision tasks. The Image Acquisition Assistant allows to quickly configure the connection to an image acquisition device. The Matching Assistant acts as a comfortable front-end to HALCON’s shape-based matching. It replaces HMatchIt. The assistants automatically generate the corresponding HDevelop code.
