    • A method and apparatus for pattern recognition comprising comparing an input signal representing an unknown pattern with reference data representing each of a plurality of pre-defined patterns, at least one of the pre-defined patterns being represented by at least two instances of reference data. Successive segments of the input signal are compared with successive segments of the reference data and comparison results for each successive segment are generated. For each pre-defined pattern having at least two instances of reference data, the comparison results for the closest matching segment of reference data for each segment of the input signal are recorded to produce a composite comparison result for the said pre-defined pattern. The unknown pattern is the identified on the basis of the comparison results. Thus the effect of a mismatch between the input signal and each instance of the reference data is reduced by selecting the best segments from the instances of reference data for each pre-defined pattern.
    • 一种用于模式识别的方法和装置,包括将表示未知模式的输入信号与表示多个预定义模式中的每一个的参考数据进行比较,所述预定义模式中的至少一个由至少两个参考数据实例表示。 将输入信号的连续段与参考数据的连续段进行比较,并生成每个连续段的比较结果。 对于具有至少两个参考数据实例的每个预定义模式,记录输入信号的每个段的参考数据的最接近的匹配段的比较结果,以产生用于所述预定义模式的复合比较结果。 未知模式是根据比较结果确定的。 因此,通过从每个预定义模式的参考数据的实例中选择最佳段来减少输入信号和参考数据的每个实例之间的失配的影响。
