Recognition of Words Expressed by Japanese Sign Language and Generation of Japanese Sign Language Animation using Thermal Image Processing

Details

This book describes two approaches for supporting hearing-impaired people. The former is a basic method for sign language recognition by a computer. The latter is a basic method for sign language animation. We exploit thermal image processing in both methods. A basic method for recognizing sign language has been developed with thermal image processing. In this method, a pair of traces of two hands, which corresponds to a word in Japanese sign language, is input into a computer as sequential coordinates with thermal image processing. Then the word is recognized by finding the most similar pair of traces in the database to that expressing the word. Forty-seven Japanese words in sign language were recognized with good accuracy.
