Title: METHOD AND APPARATUS FOR LABEL DETECTION
Abstract:
A method of label detection includes: obtaining a template for a label having a sub-region containing a visual feature, the template defining (i) a label geometry, and (ii) a sub-region geometry relative to the label geometry; obtaining an image; generating a feature mask from the image, the feature mask indicating areas of the image containing the visual feature; for each of a plurality of template positions within the feature mask, determining a score based on a degree of matching between the sub-region geometry and a respective subset of the areas; and selecting and presenting a label location within the image based on the scores.
