1. A method of reducing specular reflection, comprising the steps of: acquiring an optical image of a target object, wherein said optical image includes a plurality of pixel values; setting boundaries in said image that define a region where specular reflection will be reduced; setting a threshold pixel value; evaluating each of said plurality of pixel values within said region to determine whether each of said pixel values exceed said threshold pixel value; and replacing each of said pixels values that exceed said threshold pixel value with a replacement value.
