摘要

In this paper we develop a new form of filter, designed to eliminate downward noise spikes from SPM images before they are reconstructed to remove tip shape features. It is shown that a flat surface function is the optimum structuring element for the removal of downward noise and that this should have a dimension equal to or less than the radius of curvature of the probing tip. By using the operation 'closing' the original SPM image is operated on with such a function. The holes present in the image which are smaller than the apex of the tip, as given by the downward noise of images, are eliminated. This operation is called a 'closing filter'. Consequently, this filter is able to enhance the existing standard method, morphological reconstruction, when generating reconstructed images. In comparison, the performance of this filter was found to be significantly better than that of the median filter. Furthermore, the image artefact due to the tip-surface geometrical interaction was simulated and quantified. [References: 18]
