Automated Pharmaceutical Pill Identification

摘要

A pill identification system identifies a pill type for a pharmaceutical composition from images of the pharmaceutical composition. The system extracts features from images taken of the pill. The features extracted from the pill image include color, size, shape, and surface features of the pill. In particular, the features include rotation-independent surface features of the pill that enable the pill to be identified from a variety of orientations when the images are taken. The feature vectors are applied to a classifier that determines a pill identification for each image. The pill identification for each image is scored to determine identification for the pharmaceutical composition.

主权项

1. A computer-implemented method for identifying a pharmaceutical composition, the method comprising:
accessing at least one image of the pharmaceutical composition, wherein each image comprises a distinct image of the pharmaceutical composition; extracting features from each image of the pharmaceutical composition, the features including a rotationally-independent measure of surface features of the pharmaceutical composition in the image; generating a feature vector associated with each image of the pharmaceutical composition that includes the features extracted for that image; applying at least one classifier to each of the feature vectors to determine at least one classification associated with each image; and determining a pill identification by accumulating the at least one classification for each image.
