METHOD AND APPARATUS FOR IDENTIFYING AN OBJECT USING AN ORDERED SEQUENCE OF BOUNDARY PIXEL PARAMETERS

摘要

The present invention relates to a method and apparatus for identifying an examined object having a discernible boundary. An image of the object is formed (34) and segmented into a plurality of pixels (36). The boundary of the object in the image is detected (40) and the parameters of the boundary pixels form an ordered sequence: p1...pk...pN, where p1 is the parameter value of the first boundary pixel; where pN is the parameter value of the last boundary pixel; N is the total number of boundary pixels and k is the index to the N pixels. The pk data point is determined (42) such that k satisfies the relationship (I): i-1/M < k/N <= i/M, where M is the total number of quantile partitions and i is the ith quantile partition. The object is identified based upon the pk data point value, which is the ith quantile in M partitions developed from the above relationship.
