<b><u>Project abstract :</u></b><br>
</p>
<blockquote>
<p>The main objective of the thesis is to measure the impact of
a change in the illumination spectrum in the physical domain
(spectral imaging) and in the perceptual domain (imaging in
perceptually uniform spaces, such as CIELAB). The project
hypothesis is that a change in the illumination spectrum of a
scene has an impact on the complexity measurement obtained by
color or spectral cameras and/or on the perception of
observers.</p>
<p>Based on the state of the art and the results obtained in the
ICONES team on color and spectral image analysis, the PhD
student will develop various attributes for measuring the
textured appearance and complexity of acquired surfaces. The
PhD student will also take part in the experimental process
(measurements and psycho-visual experiments). The complexity
measurements calculated in the perceptual and physical domains
will then be correlated with the results of the psycho-visual
experiments. These results will be compared and shared with
those obtained by the NRA (National Research Agency) project
partners. They will also be promoted at international level in
conjunction with the CIE (International Commission of
Lightning).<br>
