Abstract
This is a computer-assisted x-ray screening device - using certain blurring of the details in the image - that helps ensure greater degree of privacy of the passengers of airplanes in an airport when their whole bodies are screened by x-ray for air travel safety.
Description
Patent Application : AIRPORT X-RAY SCREENING PRIVACY
Inventor : Bibhuti Bhusan BARDHAN
Page - 2 (of 6) Bacl~round of Invention Lately, the governments and airport authorities, and such other related agencies, are considering increasing the efficiency of screening of airplane passengers by introducing a whole-body x-ray screening of the passengers to detect any object(s), considered unsafe, hidden on or inside the bodies of passengers before they board planes for travel.
However, there is a concern for loss of privacy of the said passengers when so screened as this not only makes the said "unsafe" objects visible but also reveals substantial details of parts of the bodies of these passengers (that may not be necessary for the screening) to the screener, and hence to the authorities and such other agencies.
One of the ways of preventing this problem is by making the unnecessary details of the screened objects (such as details of the body parts) blurred or inconspicuous through computerized mechanisms. This result may also be achieved by some other processes like making the whole image on the screen distorted, such as seen when viewed through purposely constructed crooked lenses or reflected over purposely built distorted or uneven mirrors. When any "unsafe" object is suspected, the local area on the screen may be un-distorted or evened out - all by computerized means, as and when required, in order to identify and define the said "unsafe" objects) more clearly.
This is the object of the present invention.
Patent Application : AIRPORT X-RAY SCREENING PRIVACY
Inventor : Bibhuti Bhusan BARDHAN
Page - 3 (of' 6) Description of Invention Like numbers in parenthesis here refer to like numbers in the drawings in the Diagrams A, B, C,D,E&F.
Diagram A shows a straight and undoctored x-ray image of a prospective airline passenger. Some of the details of the body parts of this passenger seem to be visible in this picture.
Diagram B shows a doctored or altered version of the image in Diagram A; the details of any body part is not clearly discernible to the eye. Here, the inset (11) is an area of interest, which seems to show some image of an x-ray opaque suspicious object ( 1 ).
Diagram C is enlargement of the inset (11) in Diagram B, showing within it the said suspicious object (2) a little more clearly.
In Diagram D, the said suspicious object (3) is identified and defined even more clearly after the distortion (shown in Diagrams B & C) of the picture is cleared (back to the clarity of the original image as shown in Diagram A).
Such blurring, smudging, masking or obscuring of details of body parts in the x-ray images may be achieved by various other means and through the computer; all these methods and mechanisms would be considered within the scope of the present invention.
However, this obscuring of details would not be employed so as to make the "unsafe"
objects) unrecognizable. Therefore, the degree of obscuring of the details of the x-ray image would have to be balanced between making the body parts less recognizable and keeping the "unsafe" objects) still well or reasonably recognizable.
Diagrams E & F show another way of making the x-ray image less objectionable, namely, by making the empty dark (black) background (5) of the whole frame in Diagram E more or less of the same colour as the overall colour of the images of the body (4) & (44), which is around a greyish colour (55) as represented in Diagram F.
(It should be mentioned here that due to technical difficulty in drawing the colour (55) here it was not be possible to create the exact colour intended, that is, simulating the overall colour of the images of the body parts (4) & (44); in an ideal drawing, the colour (55) should approach the overall colour of the images of the body parts (4) or (44).) Over-exposure and under-exposure of the x-rays may also be used in order to produce less discernible details of body parts in the image.
