Abstract
The purpose of the current work is to develop, test and compare different methods
for the detection of the angles of the head. To achieve good head estimation this
project has been divided in two stages. In the first stage, different face detection
and tracking techniques have been implemented, as well as a face point clouds
constructor. In the second stage, 4 different techniques for head pose estimation
have been implemented and tested using the “ICT 3D HeadPose Database [75, 76]”
to evaluate their behaviors and make a comparison between their results.
After a presentation and analysis of the main state-of the-art head pose estimation
algorithms, we present our four selected methods based on the use of 3D images
(PCA, cylinder fitting using RANSAC, cylinder fitting doing an exhaustive search of
the cylinder axis and ICP). These methods are completely automatics, so they do
not need any training.
In order to evaluate the results and identify potential error sources, two different
analyses have been done: (1) a global analysis for each method tested over the
whole database and (2) a specific analysis using different techniques over some
subjects of the database. From the results of these analyses, a comparison between
the four methods is made.
