Resumen:
This work presents a methodology for automatic colour allocation in
thermographic images which is based on two thermograms, one with an Iron
colour palette for segmentation and the other in grayscale for thermal
analysis through the thermal matrix. With the fusion of both procedures,
a palette of colours image is obtained. The colour palette allows
characterising the thermography in a controlled manner and gain a better
interpretation of the colours. Likewise, the colour palette permits to
work in temperature level. With this proposed methodology, it is
possible to assign any colour desired. An experiment to induce human
emotions (joy, disgust, anger, fear, and sadness) was carried out to
prove the application of this proposed method. In a quantitative way, a
thermal index of emotions that shows the emotion concerning the baseline
was obtained, which correlates with the colours assigned to the new
image. Each emotion was associated with one colour. The results attained
from both the thermal index of emotions and the hue allocation show the
applicability and validation of the proposed palette; thus, it could be
employed in any application of thermographic analysis.
