System and method for identifying objects of interest in image data
First Claim
1. A method of identifying a threat object of interest in X-ray image data, wherein the image data comprises a plurality of grey-scale or color pixel values, comprising:
- receiving the X-ray image data; and
applying at least one predetermined bifurcation transform to the X-ray image data to effect divergence of the threat object of interest from other objects, wherein said at least one predetermined bifurcation transform is determined by applying at least one initial bifurcation transform to X-ray image data containing a known threat object that is substantially similar to said threat object of interest, and adjusting said at least one initial bifurcation transform so that the known threat object diverges from other objects in the X-ray image data once said predetermined bifurcation transform is applied to said X-ray image data.

Abstract
A system and method for identifying objects of interest in image data is provided. The present invention utilizes principles of dynamic discontinuity in which objects in images, when subjected to special transformations, will exhibit radically different responses based on the chemical properties of the imaged objects. Using the system and methods of the present invention, certain objects that appear indistinguishable from other objects to the eye or computer recognition systems, or are otherwise statistically identical, generate radically different and statistically significant differences that can be easily measured.

20. An apparatus configured to identify a threat object of interest in X-ray image data wherein the image data comprises a plurality of grey-scale or color pixel values, comprising:
-
an input device configured to receive the X-ray image data; and an image transformation recognition system configured to apply at least one predetermined bifurcation transform to the X-ray image data to effect divergence of the threat object of interest from other objects, wherein said at least one predetermined bifurcation transform is determined by applying at least one initial bifurcation transform to X-ray image data containing a known threat object that is substantially similar to said threat object of interest, and adjusting said at least one initial bifurcation transform so that the known threat object diverges from other objects in the X-ray image data once said predetermined bifurcation transform is applied to said X-ray image data.

21. A method of creating a bifurcation transform for a class of threat objects, comprising:
-
selecting a point operation; performing said point operation on a subset of images, wherein said subset of images includes at least one image comprising a plurality of grey-scale or color pixels and containing an object in said class of threat objects; and adjusting said point operation and repeating said selecting and said performing step until said point operation bifurcates said object. - View Dependent Claims (22, 23)
