Abstract
In continuous sign language recognition, reference sign language patterns of good quality are generated. Continuous sign language patterns and reference sign language patterns are efficiently compressed. The compressed continuous sign language patterns are sequentially and directly matched with the compressed reference sign language patterns to recognize the sign language at high speed and with high precision. A reference sign pattern generating unit generates a reference sign language pattern by normalizing sample patterns while taking into consideration of their nonlinear compression/expansion and by calculating an average of the sample patterns. A continuous sign language recognition unit recognizes a continuous sign language at high speed by sequentially matching the continuous sign language of time sequential patterns with reference sign language patterns while allowing nonlinear expansion and compression in the time domain. A sign language translation system is provided in which a sign language as well as the facial expression or emotion of a sign language user is recognized and converted into a spoken language with emotion, and transferred in the form of texts, voices, sign …
