1. A method for facilitating an enhancement of a visibility of an object in an x-ray image, said method comprising: generating an x-ray image including at least one object; generating an estimate of a background surrounding the at least one object; subtracting the background estimate from the x-ray image to generate an estimate of pixel intensities due the object; mapping the estimate of pixel intensities due to the object; and combining the mapped estimate of pixel intensities due to the object and the x-ray image to generate an enhanced image.
