Visual object segmentation tools
- By exploiting the distinct skin-like color that corresponds to a
particular sector of the HSV color space and their elliptical
- By employing a hierarchical knowledge-based pattern
recognition system that uses mosaic images.
- Assumptions employed: the mirror-symmetry of the face,
biometric analogies, key facial features are related to image local
minima identifiable in the vertical image profile or can be
modeled by simple geometrical curves.
- Example-based approaches based on Support Vector Machines.
Snakes can be used to track the face contour and block matching techniques can be used to track facial features.
