Overview
Model Name: barcode-localizer
The Barcode Localizer model is designed to detect 1D and 2D barcodes within each image. It handles use cases involving barcodes printed on documents, packaging, and direct part marking (DPM) barcodes. Typically, the detected barcode regions can be passed to a separate barcode decoder component for further processing.
New in v5.0.1
- Improves detection accuracy for low contrast images and for low contrast images and composite barcodes.
Requirements
Operating System: Android 14 or higher. For specific OS versions, refer to AI Data Capture SDK Release Notes from the Zebra support portal.

Technical Details
- Input Resolutions Recommended:
- 640x640
- 1280x1280
- 1600x1600
Note: This model is pre-cached with the recommended resolutions above. Any other resolutions chosen will result in higher model load times.
Note: For input resolutions beyond these recommendations, the model load time could be higher.

Measurements Notes:
- All measurements are estimations.
- Measurements were conducted using the Zebra TC53 device equipped with the Qualcomm 6490 chipset operating on the DSP AI accelerator.
- Images were 4MP Resolution under 300 Lux lighting conditions.
- Measurements were based on a UPCA 13 mil barcode.
- Estimates reflect detection times only and do not include decode time.
