Method and system for identifying a liquid product in luggage or other receptacle
First Claim
1. A method comprising:
- a. receiving image data from at least one radiographic image of a receptacle, the image data being generated by scanning the receptacle with a radiation scanner;
b. processing the image data using program code executed by a computer to detect if a liquid product is present in the receptacle, the liquid product being comprised of a container holding a body of liquid, wherein processing the image data includes using the program code executed by the computer to detect a liquid product signature in the image data;
c. releasing at an output of the computer detection results obtained by processing the image data.

Abstract
A method, an apparatus and a system are provided for determining if a piece of luggage contains a liquid product comprised of a container holding a body of liquid. The piece of luggage is scanned with an X-ray scanner to generate X-ray image data conveying an image of the piece of luggage and contents thereof. The X-ray image data is processed with a computer to detect a liquid product signature in the X-ray image data and determine if a liquid product is present in the piece of luggage. A detection signal is released at an output of the computer conveying whether a liquid product was identified in the piece of luggage. The detection signal may, for example, be used in rendering a visual representation of the piece of luggage on a display device to convey information to an operator as to the presence of a liquid product in the piece of luggage.
