Method and apparatus for image processing to avoid counting shelf edge promotional labels when counting product labels

摘要

A method and apparatus for image processing to avoid counting shelf edge promotional labels when counting product labels. Shelf edges are identified by detecting shelf edge content in a captured image by comparing the image to reference images of shelf edge content. Detected occurrences of shelf edge content are demarcated using a geometric pattern having corners at coordinates corresponding to positions around the identified shelf edge content. Corresponding corners are grouped into clusters, and the clusters are analyzed to define the upper and lower bounds of a shelf region in the image.

1. A method for identifying edge regions in an image, comprising:
receiving an image containing at least one edge region, the edge region containing patterned content; identifying, using a processor, individual occurrences of the patterned content by comparing sections of the image to a reference image of the patterned content; demarcating, using the processor, each identified individual occurrence of the patterned content in the image with a commonly oriented geometric pattern having at least one corner associated with a first side of the corresponding pattern content and at least one corner associated with a second side of the corresponding patterned content; and splitting, using the processor, the corners into first and second sets, with the first set indicative of a first boundary of an edge and the second set indicative of a second boundary of the edge; and generating, using the processor, an indication of the first and second boundaries to enable exclusion of the edge from a recognition process.
