Abstract
Systems and techniques are described herein for quick response (QR) code decoding. For example, a computing device can apply a filter to a QR code to blur the QR code; determine one or more areas of the filtered QR code that are associated with an error based on a light intensity variance of the one or more areas being above or below a variance threshold; and apply erasure correction to the one or more areas.

An apparatus for quick response (QR) code decoding, the apparatus comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to:
- apply a filter to a QR code to blur the QR code;
- determine one or more areas of the filtered QR code that are associated with an error based on a light intensity variance of the one or more areas being above or below a variance threshold;
- and
- apply erasure correction to the one or more areas.
An apparatus for quick response (QR) code decoding, the apparatus comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to:
- process a QR code, using a machine learning model, to generate an error confidence map including an indication that one or more areas of the QR code are associated with an error;
- parse the error confidence map to determine a position of the one or more areas of the QR code associated with the error;
- and
- apply erasure correction at the position of the one or more areas associated with the error.
