Latest Patents

Challener holds a patent for a method of image encoding and synthesis. This patent involves processing visual images of a speaker's face to extract still frames and typical mouth shapes during a learning sequence. The encoding of sequences for transmission or recording is achieved by matching changing mouth shapes to a predefined set, generating codewords that identify them. Additionally, these codewords can accompany real or synthetic speech using a lookup table that relates speech parameters to codewords. In a receiver, still frames and mouth shapes are stored, and received codewords are used to select successive mouth shapes to be incorporated into the still frame.
