Abstract: A method and system for performing indicia recognition includes obtaining, at an image sensor, an image of an object of interest and identifying at least one region of interest in the image. The region of interest contains one or more indicia indicative of the object of interest. The processor then determines positions of each region of interest and further determines a geometric shape based on the positions of each of the regions of interest. An orientation classification is identified for each region of interest is based on a respective position relative to the geometric shape for reach region of interest. The processor then identifies and performs one or more transformations for each region of interest, with each transformation determined by each regions respective orientation classification. The processor then performs indicia recognition on each of the one or more transformed regions of interest.

Abstract: A method of extracting a target text string includes: at a controller of a data capture device, obtaining an image of an item having the target text string thereon; at the controller, selecting a search area from the image; at the controller, processing the search area via a primary image classifier, to identify a candidate target string; at the controller, validating the candidate target string based on a validation criterion; and displaying the validated candidate target string via an output device of the data capture device.
