Abstract
It is frequently necessary to preprocess images to remove the background. In this paper a controlled study of background removal by different types of filter is presented. The bandpass characteristics of each type of filter are optimized, and it is shown that the morphological top- hat transform as usually implemented is very sensitive to noise but that replacing the opening (or closing) step by a median sieve (a cascade of median filters with structuring elements of increasing size) removes the background in a much more robust fashion.
