Systems and methods are described, including a system () for automatically ascertaining a height characteristic of a contaminant () on a travel surface (). The system () comprises an illumination and imaging device (). At a first time, when the travel surface () is generally free of contaminant, the illumination and imaging device () illuminates the travel surface () with at least one light beam (), and images at least one impingement of the at least one light beam (). At a second time, when the travel surface () is covered by a layer of contaminant (), the illumination and imaging device () illuminates the travel surface with a light beam (), and images an impingement of the light beam on an impingement surface (). In response to the imaging, a computer () calculates the height characteristic of the contaminant. Other embodiments are also described.

A method of processing an image having a plurality of picture-elements is disclosed. The method comprises: preprocessing the image to selectively enhance contrast of some picture-elements of the image, and employing a companding procedure for the preprocessed image, thereby providing a processed image. The contrast enhancement optionally and preferably features a mapping function having a plateau region for diminishing image data with intensity levels below an intensity threshold, thereby providing a preprocessed image.
