Release Notes - DynamsoftCaptureVisionBundle

2.6.1000 (01/03/2025)

Highlights

Enhanced document detection delivers more reliable results, particularly for single-document scenarios. Key improvements include:
- Strengthened detection algorithms for greater accuracy and robustness.
- Optimized parameter configurations for better adaptability across diverse scenarios.
- Refined cross-verification rules to ensure more consistent detection outcomes.
Introduced a feature to track and accumulate recognized barcodes across multiple frames in real-time video, enabling seamless multi-barcode recognition.

Changelogs

New

Added a new mode, CICM_EDGE_ENHANCEMENT, to the ColourConversionModes parameter, designed to enhance edge details when converting a color image to grayscale.
Introduced the concept of LogicLines to enhance the processing and analysis of document structures.
- Added a new value, IRUT_LOGIC_LINES, to the IntermediateResultUnitType enumeration.
- Added a new function onLogicLinesReceived to the class IntermediateResultReceiver which will be called when logic lines have been received.
- Added a new class, LogicLinesUnit, to represent an intermediate result unit containing logic lines.
Added the getCrossVerificationStatus function to both the DetectedQuadResultItem and NormalizedImageResultItem classes, along with a new EnumCrossVerificationStatus enumeration, to retrieve the cross-verification status of the result.
Added the getParameterTemplateCount and getParameterTemplateName functions to the CaptureVisionRouter class to improve accessibility and usability of templates.
Added to-the-latest overlapping feature. You can use enableLatestOverlapping function of MultiFrameResultCrossFilter class to enable this feature.
Added the getFieldRawValue method to the ParsedResultItem class to retrieve the raw value of the field.

Fixed

Fixed a bug in TextZone caused by the absence of a custom copy constructor, which led to improper memory management with the default copy constructor.
Fixed a bug in DPM mode where the isMirrored value in the BarcodeResultItem was not correctly assigned.
Fixed a bug where DotCode could not be decoded in certain scenarios.
Small fixes and tweaks.

Changed

Updated the parameter configurations for the DetectDocumentBoundaries_Default and DetectAndNormalizeDocument_Default preset templates to default to single-document mode.
Changed default value of ExpectedDocumentsCount parameter from 0 to 1 to better support single-document mode.
Changed default value of CornerAngleRange parameter from [70, 110] to [60, 120] to support a wider range of document capture angles.
Modified the return logic for DetectedQuadResultItem and NormalizedImageResultItem when ResultCrossVerification is enabled. Previously, only verified results were returned; now, results are returned regardless of verification status, and the results include a CrossVerificationStatus to indicate the verification state.
Removed the LineExtractionModes parameter and replaced it with ShortlineDetectionMode and LineAssemblyMode for more flexible and precise configuration.
