ABSTRACT:
This report describes our approach to localization of the face from the profile. It contains methods for finding interesting parts in the face. Interesting parts are: chin, lips, nose, eye (we see only one from the profile). Our algorithm consists of 6 steps:
- Edge detection
- Vectorization of edges
- Computing a curvature for each edge
- Finding a local extrema on a curvature
- Computing features for the extrema
- Classification
Limitations of the input image and discussion about the choice of our approach are in the initial chapters. The central part of this report deals with detailed description of our approach. The discussion about the obtained results is reported at the end of our document.
