Development in Signer-Independent Sign Language Recognition and the Ideas of Solving Some Key Problems

Signer-Independent sign language recognition is an unavoidable problem that must be solved in order to promote the practicality of sign language systems. In the signer-independent sign language recognition research, the lack of training data and the signer-independent sign language data variation bring a challenge to the effectivity of the existent research frame. This paper proposes a new research frame for signer-independent sign language recognition, and provides the strategy and ideas to solve the problem. Finding resolution to these problems is significant not only to the research on Chinese sign language recognition but also to other related fields.
