1. De- rotating face - Procedure Eye detection and mouth detection
Measuring angle of face
Rotating the face back to upright frontal position

3. EyemapC
High Cb and low Cr values are found the eyes(EyemapC)

4. EyemapL
Eye contains both dark and bright pixels in the luminance component(EyemapL)

5. Eyemap Eyemap=(EyeMapC)AND(EyeMapL)
->Normalize Eyemap to the range [0,255]

6. Construction of eye map

7. MouthMap
The color of mouth region contains more red component and less blue component than other facial region.
Hence, Cr>Cb

8. Construction of the mouth map

15. More results

16. Advantages Fast to get result (1.7 seconds)
It can be related to face detection.

17. Further study
Better lightening compensate techniques is required->Very sensitive to lightening problems
Different method to measure angle
-> Eyes can’t always be detected.(Sunglasses, small eyes, closed eyes, etc)
