1. A method of electronically inspecting baggage, comprising:
- generating scan data representative of a piece of baggage;
extracting at least one of contour and surface information from the scan data, the at least one of contour and surface information representative of an object within the baggage;
converting the at least one of contour and surface information to spherical harmonic coefficients;
performing a weighted comparison of the spherical harmonic coefficients to an object database to identify an object match, the object database comprising spherical harmonic coefficients representative of shapes of known objects; and
presenting the object match.

Abstract
A method and system of electronically inspecting baggage comprises generating scan data representative of a piece of baggage. At least one of a contour and a surface is extracted from the scan data, and the at least one of a contour and a surface is representative of an object within the baggage. An object database comprises data representative of shapes of known objects, and the at least one of a contour and surface is compared to the object database to identify an object match which is presented.

14. A system for electronically inspecting baggage, comprising:
-
a database to store scan data acquired while scanning a piece of baggage; an object database to store spherical harmonic coefficients corresponding to known objects; a workstation for generating a plurality of spherical harmonic coefficients of an object of interest in the piece of baggage and performing a weighted comparison of the spherical harmonic coefficients of the object of interest in the baggage to the spherical harmonic coefficients corresponding to the known objects to identify an object match; and a display for displaying information related to the object match. - View Dependent Claims (15, 16, 17, 18, 19)

20. A non-transitory computer readable medium storing an application for use to inspect baggage, where scan data has been generated that is representative of a piece of baggage, the scan data being stored at a first memory, the application comprising instructions configured to direct a computer to:
-
obtain the scan data from the first memory; extract at least one of contour and surface information from the scan data, the at least one of contour and surface information representative of an object within the baggage; convert the at least one of contour and surface information to spherical harmonic coefficients; perform a weighted comparison of the spherical harmonic coefficients to an object database to identify an object match, the object database including spherical harmonic coefficients of known objects; and present the object match on a display. - View Dependent Claims (21, 22)
