Abstract :
To solve the problem of detecting and tracking lip in lipreading. A new real time lip detection method based on the discrepancy of skin and lip on chrominance and R/G was proposed. First, find out skin area based on threshold value in HSV color model, then look for the lip area based on the individual chrominance property of skin and lip adaptively, filted with R/G filter lip was located. Experiments on service robot demonstrate that the method is effective, fast and fit for detecting and tracking lip in real time lipreading application.
