**AI-Powered Barcode Detection & Decoding**
18
+
- 🧠 **First-to-Market AI Localization**: Revolutionary `OneDLocalization` and `DataMatrixQRCodeLocalization` neural network models for superior detection of **blurred/low-resolution 1D codes** and **DataMatrix/QR codes with missing or damaged finder patterns**
19
+
- ⚡ **Specialized Decoders**: Cutting-edge `EAN13Decoder` and `Code128Decoder` models deliver unprecedented accuracy for **blurred and long-distance** scenarios
20
+
- 🔍 **Enhanced Clarity Processing**: Completely redesigned `OneDDeblur` model with superior **motion blur and focus blur** recovery algorithms
21
+
- 🎯 **Flexible Model Configuration**: Advanced `ModelNameArray` parameter enables on-demand model loading and precise selection for specific barcode scenarios
22
+
23
+
**Precision Control**
24
+
- ⚙️ **Granular Deblur Methods**: Fine-tuned `DM_DEEP_ANALYSIS` with specialized method control - `OneDGeneral`, `TwoDGeneral`, and `EAN13Enhanced` for targeted optimization
25
+
- 🎯 **Smart Barcode Counting**: New `ExpectedBarcodesCount` parameter enables **format-specific quantity control** and **early termination optimization** for known-quantity scenarios
26
+
- 🔍 **Advanced Region Detection**: New `RPM_GRAY_CONSISTENCY` mode enables precise region detection based on **grayscale uniformity** and **local consistency** for document and label processing

### Changed
47
+
48
+
- Updated the default value of parameter [`MaxThreadsInOneTask`]({{ site.dcvb_parameters_reference }}barcode-reader-task-settings/max-threads-in-one-task.html) from 4 to 0 (auto-detection).
49
+
- Updated the default value of parameter [`IncludeTrailingCheckDigit`]({{ site.dcvb_parameters_reference }}barcode-format-specification/include-trailing-check-digit.html) from 1 to 0.
50
+
- Deprecated argument `DeblurModelNameArray` of parameter [`DeblurModes`]({{ site.dcvb_parameters_reference }}barcode-reader-task-settings/deblur-modes.html), use `ModelNameArray` instead.
51
+
- Deprecated method `AppendModelBuffer` of class [`CaptureVisionRouter`]({{ site.dcvb_cpp_api }}capture-vision-router/capture-vision-router.html), use [`AppendDLModelBuffer`]({{ site.dcvb_cpp_api }}capture-vision-router/auxiliary-methods.html#appenddlmodelbuffer) instead.
