Lips on closed mouth

This is also a closed-mouth detector (closed-mouth detection software).

The Brief Growing-up History of PL Lip/Mouth Detectors.

Since the computational cognition ability of the physical linguistic image processing engine, each PL vision detector is evolving overtime based on its performance in real-life applications, therefore, we present some brief snapshot of the evolution of this PL visual detector at different growing stages. By inspecting the growing processes of PL vision detectors, we can observe the highly scaled-up abilities of PL vision detectors under constant updating and developing by Yang's Scientific Research Institute.

Stage 1: Finished on December 23, 2005. Only four directions of closed mouths can be detected with some false alarms.



Stage 2: Finished on January 7, 2006. Only four directions of closed mouths can be detected with lower false-alarm rate.

Lips on open mouth

This is also an open-mouth detector (open-mouth detection software).
