Claim One:
1. A method for determining whether a first product has been successfully purchased at a check-out register including a product purchase scanner, the method comprising the steps of: a computer identifying in a video record a first movement of a first product adjacent to a scanner and an approximate time at which the first product was moved adjacent to the scanner; the computer determining that the scanner did not record a purchase transaction with in a predetermined time of the time at which the first product was moved adjacent to the scanner as identified in the video record; the computer identifying in the video record a second movement of a second product adjacent to the scanner and an approximate time at which the second product was moved adjacent to the scanner; the computer determining that the scanner did not record a purchase transaction with in a predetermined time of the time at which the second product was moved adjacent to the scanner as identified in the video record; the computer measuring a difference in time between the time of the first movement of the first product adjacent to the scanner and the time of the second movement of the second product adjacent to the scanner; and the computer, using a support vector machine that has been trained with a training video record that depicts a plurality of movements of products adjacent to one or more scanner, determining a likelihood that the first product was successfully purchased based in part of the difference in time between the time of the first movement of the first product adjacent to the scanner and the time of the second movement of the second product adjacent to the scanner.
