Abstract

A method, software and apparatus are disclosed to improve security by helping determine whether a bag contains a prohibited item. A CT scan of a bag is performed to generate an image. An artificial intelligence algorithm is performed to classify portions of an image as normal and portions of said image as abnormal. A first type of image processing for said normal portion(s) of said image. A second type of image processing for said abnormal portion(s) of said image wherein said second type of image processing is different from said first type of image processing. The normal portion(s) of the image are displayed with said first type of image processing and said abnormal portion(s) of the image are displayed with said second type of image processing to a TSA Agent for analysis of said image. In the preferred embodiment, the TSA Agent will perform the analysis on an extended reality head display unit.

Claims (64)

1. A system comprising:

a memory;

a processor;

a display;

a communication interface;

an interconnection mechanism coupling the memory, the processor and the communication interface; and

wherein the memory is encoded with an application providing image processing, that when performed on the processor, provides a process for processing information, the process causing the computer system to perform the operations of:

performing artificial intelligence algorithm to classify portions of an image as normal and portions of said image as abnormal;

performing a first type of image processing for said normal portion(s) of said image;

performing a second type of image processing for said abnormal portion(s) of said image wherein said second type of image processing is different from said first type of image processing; and

displaying on said display said normal portion(s) of said image with said first type of image processing and said abnormal portion(s) of said image with said second type of image processing.

2. The system of claim 1 further comprising dividing said image into said normal portion(s) and said abnormal portion(s) via a segmentation algorithm.

3. The system of claim 1 further comprising dividing said image into said normal portion(s) and said abnormal portion(s) via a halo-type modified segmentation algorithm.

4. The system of claim 1 further comprising delineating said abnormal portion(s) via a geometric shape surrounding said abnormal portion(s).

5. The system of claim 1 further comprising wherein said second type of image processing is determined by a danger of said abnormal portion(s).

6. The system of claim 1 further comprising wherein said second type of image processing is determined by a certainty of classification of said abnormal portion(s).

7. The system of claim 1 further comprising wherein displaying normal portion(s) of said image with said first type of image processing and said abnormal portion(s) of said image with said second type of image processing is performed simultaneously.

8. The system of claim 1 further comprising wherein displaying normal portion(s) of said image with said first type of image processing and said abnormal portion(s) of said image with said second type of image processing is performed sequentially.

9. The system of claim 1 further comprising providing a visual marker to notify a user of an abnormal finding as determined by an artificial intelligence algorithm.

10. The system of claim 9 further comprising wherein said visual marker comprises at least one of the group consisting of:

an arrow; and

a 3D volume cursor.

11. The system of claim 1 further comprising wherein said first type of image processing and said second type of image processing comprise at least one of the group consisting of:

performing a smoothing algorithm;

performing windowing and leveling;

performing coloring;

performing filtering;

performing transparency adjustment;

performing alteration of spatial resolution;

performing alteration of contrast resolution;

performing alteration of brightness;

performing prioritized volume rendering; and

performing tandem volume rendering.

12. The system of claim 1 further comprising wherein said image is viewed on an extended reality display.

13. The system of claim 1 further comprising wherein said image is a CT scan of a bag.

14. The system of claim 1 further comprising wherein said abnormal portion(s) are determined by said artificial intelligence algorithm to be a dangerous item.

15. The system of claim 1 further comprising wherein said abnormal portion(s) are determined by said artificial intelligence algorithm to be a contraband item.

16. The system of claim 1 further comprising wherein said abnormal portion(s) are determined by said artificial intelligence algorithm to be a suspicious/uncertain item.

17. The system of claim 1 further comprising performing analysis of said image by a user.

18. A system comprising:

a memory;

a processor;

a display;

a communication interface;

an interconnection mechanism coupling the memory, the processor and the communication interface; and

wherein the memory is encoded with an application to determine whether a bag contains a prohibited item, that when performed on the processor, provides a process for processing information, the process causing the computer system to perform the operations of:

using an image from a CT scan of a bag;

performing an artificial intelligence algorithm to classify portions of said image as normal and portions of said image as abnormal;

performing a first type of image processing for said normal portion(s) of said image;

performing a second type of image processing for said abnormal portion(s) of said image wherein said second type of image processing is different from said first type of image processing; and

displaying on said display said normal portion(s) of said image with said first type of image processing and said abnormal portion(s) of said image with said second type of image processing to a user for analysis of said image.

19. A system comprising:

a memory;

a processor;

a display;

a communication interface;

an interconnection mechanism coupling the memory, the processor and the communication interface; and

wherein the memory is encoded with an application to triage a bag that when performed on the processor, provides a process for processing information, the process causing the computer system to perform the operations of:

using an image from a CT scan of a bag;

performing artificial intelligence algorithm to classify portions of said image as normal and portions of said image as abnormal;

performing a first type of image processing for said normal portion(s) of said image;

performing a second type of image processing for said abnormal portion(s) of said image wherein said second type of image processing is different from said first type of image processing;

displaying on said display said normal portion(s) of said image with said first type of image processing and said abnormal portion(s) of said image with said second type of image processing; and

if said abnormal portion(s) are determined to be a prohibited item, selecting said bag to be triaged to an area.
