Face-TLD: Tracking-Learning-Detection applied to faces [PDF]

open access: yes2010 IEEE International Conference on Image Processing, 2010
A novel system for long-term tracking of a human face in unconstrained videos is built on Tracking-Learning-Detection (TLD) approach. The system extends TLD with the concept of a generic detector and a validator which is designed for real-time face tracking resistent to occlusions and appearance changes.

Efficient illumination independent appearance-based face tracking [PDF]

open access: yes, 2009
One of the major challenges that visual tracking algorithms face nowadays is being able to cope with changes in the appearance of the target during tracking. Linear subspace models have been extensively studied and are possibly the most popular way of

A morphological approach for segmentation and tracking of human faces [PDF]

open access: yes, 2000
A new technique for segmenting and tracking human faces in video sequences is presented. The technique relies on morphological tools such as using connected operators to extract the connected component that more likely belongs to a face, and partition ...
