Thank you for following this blog.
The Best Results first
Here are the extracted control points on top of the manually selected ones.
yellow - my extraction approach
light blue - manually selected points
- You might notice that there is a fundamental difference in the control points. I am using the mouth corners, and no nose base.
After ignoring the mouth corners and nose base, I am able to achieve the following performance
Subject M1 4th surprise face VS 43 subjects( 13 M, 30 F)
Just to reiterate, this the performance I was achieving using the manually selected control points.
43 subjects( 13 M, 30 F)
A probem emerges:
- for some images, the 3d camera was able to capture some of the slope inside the nostril. This causes the steepest edge detected to lie inside the nose as opposed to on the actual control point.
Other Trials
Here are some of the not so good results:
This is the accuracy of the system I was trying to achieve. I hoped that by using 3-dimensional data, I would have higher accuracy simply because I had higher resolution. Although the paper I followed does claim that the previous statement is true, I was unable to reproduce such stunningly high results using my more artistic approach. I think if I would have been more sophisticated with the nose width points, the creativity of the eye width control points would have been just as accurate as needed.
Thank you.
