A method for use in an object scanning process includes obtaining a reference spectrum that includes a plurality of reference peaks, and comparing the reference spectrum with an input spectrum that has a plurality of input peaks, wherein a number of the reference peaks is less than eight. A method for use in an object scanning process includes obtaining a reference spectrum that includes a plurality of reference peaks, comparing one of the reference peaks with a plurality of input peaks from an input spectrum, comparing another one of the reference peaks with the plurality of input peaks from the input spectrum, and determining a degree of similarity between the reference spectrum and the input spectrum using a result from the acts of comparing. |
