The capacity to estimate the head pose of another person is a common human ability that
presents a unique challenge for computer vision systems. Compared to face detection and …

Images containing faces are essential to intelligent vision-based human-computer
interaction, and research efforts in face processing include face recognition, face tracking …

The existence of large image datasets such as the set of photos on the World Wide Web
make it possible to build powerful generic models for low-level image attributes like color …

In this paper we present a comprehensive and critical survey of face detection algorithms.
Face detection is a necessary first-step in face recognition systems, with the purpose of …

Driver distraction and inattention are prominent causes of automotive collisions. To enable
driver-assistance systems to address these problems, we require new sensing approaches …

We present an approach that incorporates appearance-adaptive models in a particle filter to
realize robust visual tracking and recognition algorithms. Tracking needs modeling …

A technique for 3D head tracking under varying illumination is proposed. The head is
modeled as a texture mapped cylinder. Tracking is formulated as an image registration …

This paper presents an analysis of the performance of two different skin chrominance
models and of nine different chrominance spaces for the color segmentation and …

Skin colour detection is a technique very used in most of face detectors to find faces in
images or videos. However, there is not a common opinion about which colour space is the …

Optical flow provides a constraint on the motion of a deformable model. We derive and solve
a dynamic system incorporating flow as a hard constraint, producing a model-based least …
