Fuzzy data processing method and data smoothing filter

摘要: A unique data processing method and a fuzzy smoothing filter are disclosed which employ three-dimensional elliptic membership function based on the logic to remove noises from including sequence of measured points for evaluating linearity points. The evaluation is carried out by superimposing center an ellipse represented substantial central portion inputted data, factor representing summing degrees derived at respective calculating ratio ideal rotating predetermined angular distance derive that position, repeating step until peak found, determining when found as data. comprised input inputting be smoothed, multi-dimensional generator degree calculator deriving angle processors coupled receive executing operation in plurality modes, selector selecting one mode among store holding parameters supplied selector.
