A method for facilitating an enhancement of a visibility of an object in an x-ray image includes 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.
