Abstract
Example methods, apparatus, systems to perform context-based image recognition are disclosed. Disclosed example methods include comparing a first and second reference region of a reference image with a first and second region of a first captured image to determine a first and second match value. In response to determining the first and second match values satisfy a first and second threshold: associating the first captured image with a product associated with the first reference image, the product being associated with a plurality of second reference images stored in the database. Decrementing index values associated with ones of the second reference images. Removing a reference record associated with one of the second reference images from the database based on a corresponding one of the second index values satisfying a first condition, the removal of the reference record reducing the storage space required to store reference records in the database.
