Abstract:
1. A method of obtaining an image of a buried structure in an object comprising: providing a camera for imaging visual and infrared-images; providing a bounded infrared light source; partly irradiating said object by said bounded infrared light source; imaging an area of said object, by said camera, that is not irradiated by said bounded infrared light source to create an infrared image of said buried structure from infrared light scattered off the buried structure and tissue surrounding the buried structure; combining said image of said buried structure with a visual image of said object; aligning said bounded infrared light source with a visual light source; providing a first edge analysis of the infrared image; providing a second edge analysis of the visual image; comparing a first set of edges detected during said first edge analysis with a second set of edges detected during the second edge analysis; and discarding, based on the comparing the first set and second set of images, edges detected in the infrared image that are also detected in the visual image.
