<p>A method for enhancing an image, comprising the steps of constructing an input histogram corresponding to the image, the input histogram representing a pixel intensity distribution corresponding to the image; establishing a variable plateau profile to be applied to the input histogram; clipping the input histogram at the variable plateau profile to produce a clipped input histogram; constructing a cumulative histogram from the clipped input histogram; normalizing the cumulative histogram to produce a normalized cumulative histogram; and transforming the image using the normalized cumulative histogram to produce an enhanced output image corresponding to the input image, wherein at least a portion of the input image is enhanced in the output image.</p> |
