Title: IMAGE BASED COUNTERFEIT DETECTION
Abstract:

Digital images of the samples are processed to extract computer-vision features, which are used to train a classification algorithm. The computer-vision features of a test sample are evaluated by the trained classification algorithm to identify the test sample.
