<P>PROBLEM TO BE SOLVED: To determine a peak value in a histogram or sample data stream for data with a lot of noise. <P>SOLUTION: An embodiment includes: fitting a curve modeled based on an orthonormal expansion to a data sequence; acquiring a derivative curve representing change in gradients in the curve fitted to the data sequence; finding at least one root of the derivative curve; calculating a corresponding value on the curve fitted to the data sequence for each of the one root of the derivative curve; and determining a peak value in the data sequence based on the maximum value of the corresponding values calculated for the one root of the derivative curve. <P>COPYRIGHT: (C)2013,JPO&INPIT |
