The use of hand gestures provides an attractive alternative to cumbersome interface devices
for human-computer interaction (HCI). In particular, visual interpretation of hand gestures …

Face detection, which is an effortless task for humans, is complex to perform on machines.
The recent veer proliferation of computational resources is paving the way for frantic …

Two channels have been distinguished in human interaction: one transmits explicit
messages, which may be about anything or nothing; the other transmits implicit messages …

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

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 …

This paper addresses our proposed method to automatically segment out a person's face
from a given image that consists of a head-and-shoulders view of the person and a complex …

An algorithm for tracking a person's head is presented. The head's projection onto the image
plane is modeled as an ellipse whose position and size are continually updated by a local …

We designed a fast periodic visual stimulation approach to identify an objective signature of
face categorization incorporating both visual discrimination (from nonface objects) and …

Tracking research has diverged into two camps; low-level approaches which are typically
fast and robust but provide little fine-scale information, and high-level approaches which …

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 …
