Abstract In terms of the basic principle of edge operator in digital image field, a time series pattern representation based on interpolated edge operator(IEO representation) is put forward.This method, according to a measurement standard, chooses the edge point (end point) of each subpattern of time series pattern representation. The measurement standard is the combination of two submeasurement of interpolated edge operator: edge intensity and interpolation error. The IEO representation of time series can not only compress data, but also effectively restrain the influence of noise. Therefore its adaptability is relatively strong, and it can adapt different data feature environment.
