Abstract
Dual-energy backscatter x-ray shoe scanning including: pre-processing input image information received from a shoe scanning device and image calibration data received from a database to output an atomic number image; detecting at least one suspect region based off the atomic number image; identifying the at least one detected suspect region as an object class using a changeable list of attributes; and classifying the object class according to a changeable list of categories.
Claims20
A shoe scanning device, comprising:
- at least one x-ray tube oriented towards selected sides of a test subject;
- at least one detector screen oriented towards the selected sides of a test subject and configured to detect scattered photons from x-rays emitted by the at least one x-ray tube;
- a storage unit to store images from the detected scattered photons on the at least one detector screen;
- and
- a processing unit having software to detect, identify and classify concealed objects in a selected area of the test subject.
A computer-implemented method comprising:
- pre-processing, via a computing device, input image information received from a shoe scanning device and image calibration data received from a database to output an atomic number image;
- detecting, via the computing device, at least one suspect region based off the atomic number image;
- identifying, via the computing device, the at least one detected suspect region as an object class using a changeable list of attributes;
- and
- classifying, via the computing device, the object class according to a changeable list of categories.
A system comprising:
- a database to store image calibration data;
- a shoe scanning device comprising at least one x-ray and at least one detector screen;
- a pre-processing unit to receive and process image data from the shoe scanning device and to receive image calibration data from the database to output an atomic number image;
- a detection unit to detect at least one suspect region from the atomic number image;
- an identification unit to identify at least one object class from the at least one suspect region based on a changeable list of attributes and information from the atomic number image;
- and
- a classification unit to classify the object class based on a changeable list of categories.
A machine-readable medium having stored thereon a set of instructions, which when executed by a machine, perform a method comprising:
- pre-processing input image information received from a shoe scanning device and image calibration data received from a database into an atomic number image;
- detecting at least one suspect region based off the atomic number image;
- identifying the at least one detected suspect region as an object class using a changeable list of attributes;
- and
- classifying the object class according to a changeable list of categories.
