A method of price text detection by an imaging controller comprises obtaining, by the imaging controller, an image of a shelf supporting labels bearing price text, generating, by the imaging controller, a plurality of text regions containing candidate text elements from the image, assigning, by the imaging controller, a classification to each of the text regions, selected from a price text classification and a non-price text classification. The imaging controller, within each of a subset of the text regions having the price text classification: detects a price text sub-region and generates a price text string by applying character recognition to the price text sub-region. The method further includes presenting, by the imaging controller, the locations of the subset of text regions, in association with the corresponding price text strings.

Method and apparatus for detecting and interpreting price label text

Methods, systems and apparatus for detecting and recognizing graphical character representations in image data using symmetrically-located blank areas are disclosed herein. An example disclosed method includes detecting blank areas in image data; identifying, using the processor, a symmetrically-located pair of the blank areas; and designating an area of the image data between the symmetrically-located pair of the blank areas as a candidate region for an image processing function.
