Appeal No. 97-2699
Application 08/112,535
The invention relates to an apparatus and method for extracting robust, prominent
features for target tracking.
Independent claim 1 is reproduced as follows:
1. A method of analyzing a region of interest in an original image having at least one
feature to extract at least one robust feature, comprising the steps of:
passing signals representing the original image through a first filter to obtain signals
representing a smoothed image;
performing a profile analysis on the signals representing the smoothed image to
determine a signal representing a size value for any feature in the original image;
performing an analysis on the signals representing the size values determined by the
profile analysis to determine a signal representing a most frequently occurring size value;
selecting an optimal filter based on the determined signal representing the most
frequently occurring size value; and
passing the signals representing the original image through the optimal filter to obtain
signals representing an optimally filtered image having an optimally high signal-to-noise ratio.
