Abstract
Among other things, one or more techniques and/or systems for generating a three-dimensional combined image is provided. A three-dimensional test image of a test item is combined with a three-dimensional article image of an article that is undergoing a radiation examination to generate the three-dimensional combined image. A first selection region of the three-dimensional article image is selected. The three-dimensional test image of the test item is inserted within the first selection region. Although the test item is not actually comprised within the article under examination, the three-dimensional combined image is intended to cause the test item to appear to be comprised within the article.
Claims10
A method of combining an image of a threat and an image of an article, the method comprising:
- acquiring a first image representative of an article examined via radiation;
- acquiring a second image representative of a threat, wherein the threat is not represented in the first image;
- identifying, via one or more hardware processors, one or more regions of the first image, wherein the one or more regions comprise one or more of:
- one or more object regions corresponding to one or more objects, and one or more void regions corresponding to one or more voids;
- obtaining, via the one or more hardware processors, a selection region of the first image at which to insert the threat;
- processing the first image in the projection domain to obtain a property of the first image;
- processing the second image in the projection domain to obtain a property of the second image;
- merging, via the one or more hardware processors, the second image with a portion of the first image that is within the selection region, the merging comprising:
- combining, in the projection domain, the property of the first image with the property of the second image;
- and
- obtaining, via the one or more hardware processors, a merged image representative of the article including the threat.
A system, comprising:
- at least one processor;
- and
- a memory to store instructions, wherein the instructions upon execution by the at least one processor, to enable at least one hardware processor to:
- acquire a first image representative of an article examined via radiation;
- acquire a second image representative of a threat, wherein the threat is not represented in the first image;
- identify one or more regions of the first image, wherein the one or more regions comprise one or more of:
- one or more object regions corresponding to one or more objects, and one or more void regions corresponding to one or more voids;
- obtain a selection region of the first image at which to insert the threat;
- process the first image in the projection domain to obtain a property of the first image;
- process the second image in the projection domain to obtain a property of the second image;
- merge the second image with a portion of the first image that is within the selection region, the merging comprising combining, in the projection domain, the property of the first image with the property of the second image;
- and
- obtain a merged image representative of the article including the threat.
