face recognition algorithms

  • Eigenfaces or Principal Component Analysis method (PCA)
  • Fisherfaces or Linear Discriminant Analysis method
  • Kernel Methods
  • 3D face recognition methods
  • Gabor Wavelets method
  • Hidden Markov Models

The first Feng-GUI web page

Mark this day in your diary.
All sub-components are in place, and
The first Feng-GUI web page attention heatmap is up and running. (see attached)
//TODO
Enhance text localization,
there are text areas which are over looked and must be treated using "text localization" (which is a top-down attention algorithm).
Add Website AJAX 2.0 features.
More Test and Performance.
Add face recognition.

thank you for your "attention".
