SYSTEM AND METHOD OF USING IMPRINT ANALYSIS IN PILL IDENTIFICATION
First Claim
1. A method of creating a database of pill imprint images, the method comprising:
- obtaining two or more digital pill imprint images for each type of a plurality of types of pills;
aligning the two or more digital pill imprint images for each type of pill;
combining the two or more digital pill imprint images for each type of pill into a single composite imprint image for each type of pill; and
storing the composite imprint image in a database such that the composite imprint image is associated with the corresponding type of pill.

Abstract
A system and method for identifying a pill by its imprint. A digital pill imprint image for the pill is obtained and compared with one or more composite imprint images in a database. Each of the composite imprint images is a composite of two or more digital pill imprint images of a single type of pill. The composite imprint images are formed by aligning and combining the two or more digital pill imprint images for each type of pill. A match score is determined as a result of the comparing of the digital pill imprint image with each of the composite imprint images. The match score represents a degree of overlap between the digital pill imprint image and each composite imprint image. The pill is identified based on the composite imprint image having the best match score.

-
obtaining a digital pill imprint image for the pill; comparing the digital pill imprint image with one or more composite imprint images in a database, each of the composite imprint images being a composite of two or more digital pill imprint images of a single type of pill, said comparing including determining a match score for each compared composite imprint image, said match score representing a degree of overlap between the digital pill imprint image and each composite imprint image; and identifying the pill based on the composite imprint image having the best match score. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

33. A system configured to identify a pill by its imprint, the system comprising:
-
a digital camera; and a processor for receiving from the digital camera a digital image including at least one pill to be identified and for determining a digital pill imprint image for at least one of the at least one pill to be identified, the processor configured to use an imprint matching module to compare the digital pill imprint image with one or more composite imprint images in a database, each of the composite imprint images being a composite of two or more digital pill imprint images of a single type of pill. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41)
