HCC2D Decoder

This app allows you to scan and decode HCC2D and QR code symbols using your mobile camera. It is based on advanced research in high-capacity barcode technologies and provides reliable decoding.

Key features:

* Decode HCC2D color codes.
* Full support for standard QR codes.
* Real-time scanning using the camera.
* Robust detection and error correction.
* No ads and no registration required.

HCC2D is a color two-dimensional code format that increases data capacity compared to traditional QR codes while preserving their structure. By using multiple colors, each module can encode more information, enabling higher data density in a compact symbol.

HCC2D codes can be generated at: hcc2d.com

The app captures images, detects barcode regions, corrects perspective distortions, and analyzes color or intensity patterns to reconstruct the encoded data.

Notes:

* Low-quality color printing may reduce decoding performance
* Best results are achieved with screen-displayed or high-quality printed codes and a high-resolution autofocus camera.
* One-dimensional barcodes are intensionally not supported.

Nima yangiliklar

• Added support for multi-symbol streaming transfer with HCC2DST (HCC2D Streaming Transfer Protocol): the decoder reconstructs files transmitted as a sequence of HCC2D symbols even when some symbols are missing.
• Improved the HCC2D sampling and decoding algorithm, especially for printed codes.
