Abstract
A method, apparatus and computer program product train a signature encoding module (SEM) and a query processing module (QPM). The method generates a digital signature of an object of interest in a reference image provided to the SEM, and provides the SEM with at least one additional reference image that comprises a variation of the reference image and generates a digital signature for the at least one additional reference images. The method also provides the QPM with a query image and a digital signature set comprising the digital signature and the at least one additional digital signature, identifies the object of interest within the query image using the digital signature set, and modifies the SEM or QPM based upon a difference between the object of interest identified within the query image and the object of interest in the reference image or the at least one additional reference image.
