Smart barcode detection

A method comprising:

• capturing, using a camera, a plurality of images of a real scene comprising a plurality of optical patterns, wherein the plurality of optical patterns comprises a first optical pattern and a second optical pattern;
• calculating a similarity score for each of the plurality of images;
• comparing similarity scores for each of the plurality of images to a threshold value;
• selecting a first image, from the plurality of images, based on the first image having a similarity score that meets or exceeds the threshold value;
• detecting the first optical pattern and the second optical pattern in the first image;
• calculating an optical-pattern score for the first optical pattern in the first image;
• decoding the first optical pattern, after detecting the plurality of optical patterns in the first image, based on the optical-pattern score and without decoding the second optical pattern;
• and
• presenting on a display a second image and a graphical overlay on the second image to indicate the first optical pattern is intended to be decoded.

A memory device comprising instructions that, when one or more computer readable storage media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

• capturing, using a camera, a plurality of images of a real scene comprising a plurality of optical patterns, wherein the plurality of optical patterns comprises a first optical pattern and a second optical pattern;
• calculating a similarity score for each of the plurality of images;
• comparing similarity scores for each of the plurality of images to a threshold value;
• selecting a first image, from the plurality of images, based on the first image having a similarity score that meets or exceeds the threshold value;
• detecting the first optical pattern and the second optical pattern in the first image;
• calculating an optical-pattern score for the first optical pattern in the first image;
• decoding the first optical pattern, after detecting the plurality of optical patterns in the first image, based on the optical-pattern score and without decoding the second optical pattern;
• and
• presenting on a display a second image and a graphical overlay on the second image to indicate the first optical pattern is intended to be decoded.
