• Decodes multiple barcodes in the same image ROI
• Two licensing options:
  • Quick Barcode decodes the majority of codes.
  • Quick Barcode DPM offers greater robustness for decoding marks etched or dot peened on plastic or metallic surfaces

Standard Barcode

• Supports 1-D and 2-D industry standards (includes the majority of standards supported by Quick Barcode).
• High tolerance for noisy and poorly illuminated images
• Asian native language and Unicode output
• Includes Barcode Studio to set up barcode reading via Learning Assistant to help adjust optimal parameters
• Supports model training on Data Matrix for increased robustness highly damaged images
• Two licensing options:
  • Standard Barcode supports a wide variety of codes and options, and does not require training
  • Advanced Barcode offers the ability to train a Data Matrix model for increasing robustness while supporting the same codes and options as Standard Barcode.

Print Quality Grading

• Use in combination with Quick Barcode or Standard Barcode
• Includes the following standards:
  • ISO/IEC 15416 (Barcode print quality test specification - linear symbols)
  • ISO/IEC 15415 (Barcode symbol print quality test specification - Two-dimensional symbols)
  • ISO/IEC 16022 (Data matrix barcode symbology specification)
  • AIM PDM (Direct Part Mark Quality)

• Best-fitting oriented ellipse with axes lengths
• Blob roundness and elongation
• Convex area and solidity (ratio of net area to convex area)
• Feret diameters, bounding box location, size and orientation
• External and internal perimeter points, filled area
• Minimum, maximum, standard deviation of all pixels
• Gray scale centroid
• Sorting and blob selection based on calculated feature
• Robust automatic threshold algorithms
