ABSTRACT:
A method for classification of a target object having a periphery comprises the steps of: selecting a plurality of random first chords D1across the periphery of the target object;measuring each of the first chords D1to obtain a plurality of first dimensions;computing for each of the first chords D1a second chord D2across the periphery thus forming a plurality of D1, D2pairs of chords;measuring the second chords D2for all pairs to obtain second dimensions;computing for each of the pairs of first chords D1and second chords D2the ratio D1/D2of the first dimension to the second dimension to obtain a plurality of first values;computing the logarithm of the first values to obtain a plurality of logarithmic values;computing difference values by subtracting the second dimension from the first dimension for each of the pairs;recording the first values, logarithmic values and difference values in histograms;extracting a vertex lists from the histograms;combining one or more of the vertex lists to obtain a signature indicative of the classification of the object target.For each of the pairs, the second chords are orthogonal to the first chords, and the second chords share a point with the first chords and the periphery.
