Method and apparatus for image processing to avoid counting shelf edge promotional labels when counting product labels
First Claim
Patent Images
1. A method for processing images, comprising:
- receiving, at a shelf edge detection component having a processor, an image containing shelf edge content;
determining, by the processor, locations of instances of the shelf edge content by identifying interest point matches between the image and a reference image;
determining, by the processor, regions in the image corresponding to shelf edges by;
identifying a geometric pattern in the image based on the interest point matches; and
forming clusters of instances of the geometric pattern; and
estimating, by the processor, a number of shelf edges in the image based on the clusters.

Abstract
An example disclosed method includes receiving an image containing shelf edge content displayed on a shelf edge; determining a location of the shelf edge content and an apparent orientation of the shelf edge content; determining, based on the location of the shelf edge content and the apparent orientation of the shelf edge content, a region in the image corresponding to the shelf edge; and providing an output based on the image that identifies the region in the image corresponding to the shelf edge.

12. A non-transitory computer-readable storage device comprising machine-readable instructions that, when executed, cause a machine to at least:
-
receive an image containing shelf edge content; determine locations of instances of the shelf edge content by identifying interest point matches between the image and a reference image; determine regions in the image corresponding to shelf edges by; identifying a geometric pattern in the image based on the interest point matches; and forming clusters of instances of the geometric pattern; and estimate a number of shelf edges in the image based on the clusters. - View Dependent Claims (13, 14, 15, 16, 17)

18. An apparatus, comprising:
-
memory including machine-readable instructions; and a processor to execute the machine-readable instructions to perform operations including; receiving an image containing shelf edge content; determining locations of instances of the shelf edge content by identifying interest point matches between the image and a reference image; determining regions in the image corresponding to shelf edges by; identifying a geometric pattern in the image based on the interest point matches; and forming clusters of instances of the geometric pattern; and estimate a number of shelf edges in the image based on the clusters.
