ABSTRACT:
A waveform recognition system including a plurality of detectors of features having the combined presence at a plurality of instants spaced at predetermined intervals relative to each other in time of instantaneous amplitudes each satisfying respectively predetermined constraints; apparatus for assigning a plurality of labels and corresponding confidence measures to each of successive portions of the waveform in dependence on the features detected in the portions and storing each label in a buffer corresponding to the rank of the confidence with which the label is assigned relative to other labels assigned to the same portion of data and apparatus for outputting labels from that buffer containing labels assigned with the highest confidence whose confidence measures are in a predetermined relationship with those of adjacent labels in the same buffer when the confidence measures of labels in other buffers containing labels assigned with confidence measures of lower rank satisfy predetermined conditions.
