Abstract
This pattern matching system features the calculation of a weighting factor based on the variable interval between feature vector samples. On carrying out matching of two information compressed patterns, a weighted similarity measure calculator (64) calculates a weighted similarity measure by multiplying an intervector similarity measure between one each feature vector of the respective patterns by a weighting factor calculated by the use of a variable interval between each feature vector and a next previous one. A recurrence formula is calculated by the use of such weighted similarity measures instead of the intervector similarity measures. A predetermined value .delta. may be used in reducing the number of signal bits used for the recurrence formula. Preferably, a sum for the recurrence formula is restricted by two preselected values. Most preferably, an additional similarity measure is used for the recurrence formula.
