TECHNIQUES FOR IMAGING A SCANNED OBJECT

摘要

A technique for enhancing an image includes manipulating a base image to highlight pixels showing a particular material based on the energy absorption information of each pixel. In another technique, pixels in a base image are each converted to an output value to produce a converted image. Another technique allows imaging an obstructed object within a base image which is made of pixels, each representing a captured signal from a source emitting a source signal I0. An obstruction region contains pixels representing a combined signal I3 having traversed the obstructed object and an obstructive layer. Knowing a layer signal I2 representing a signal having traversed the obstructive layer outside of the obstruction region, the layer signal I2 may be removed from the combined signal I3, in order to reveal the original signal I1 representing an image of the obstructed object.

主权项

1. A method for detecting a material in an object, the method comprising:
receiving, via an input port, a base image of the object comprising one or more material to be detected, the base image being composed of pixels, each pixel comprising energy absorption information; providing in a memory, one or more reference value, each representing an energy absorption of a reference material; transforming the base image, by means of a material detection module embedded in a processor, by highlighting each of said pixels of which the energy absorption information correlates with one of said reference material stored in the memory, based on a comparison of the energy absorption information of each pixel with said one or more reference value stored in the memory, in order to produce a detection-enhanced image; and displaying, on a display screen, the detection-enhanced image having highlighted pixels corresponding to said one or more material to be detected.
