Lip Movement and Expression Database Construction for Chinese Sign Language Synthesis

To synthesize realistic and intelligible lip motion and expression for Chinese sign language,based on MPEG-4 parametric model,a kind of method for constructing lip motion and expression database was proposed.When the lip motion and expression database were used to synthesize Chinese sign language animation,compared with the previous synthesized result,the animation including gesture,lip motion and expression was more realistic and intelligible.Experimental results show that the method for constructing lip motion and expression is valid.
