Abstract
A continuous sign-language recognition apparatus and input apparatus which employ expressions of template patterns of sign-language word as well as the template patterns of sign-language word to realize high speed and highly accurate sign-language recognition. Each of component patterns constituting a template pattern of a sign-language word is expressed by a feature vector representing the pattern when the pattern is a static pattern, or by a time-series pattern of a feature vector when the pattern is a dynamic pattern. Also, using the template patterns of sign-language word, different matching methods are applied to the static and dynamic patterns for recognizing each component pattern, and the respective results are integrated on the basis of a temporal overlap of the respective component patterns to continuously recognize sign-language words.
