Resumen:
We present advancements on the analysis of infrared (IR) images of lower
limbs of patients with diabetic foot disease (DFD). Our task is to study
and identify alterations in the heat emission as result of the DFD. This
is performed through the calculation of the Spearman's correlation
coefficient. As result we found natural asymmetry values in non-diabetic
controls of 12%(+/- 7%) and 24%(+/- 16%) for the front and back
views of the limbs, respectively. In the evaluated patients we observed
a remarkable tendency towards values outside the range of natural
asymmetry found. For the purpose of validating the consistency of the
study, we use the ROC criteria, having then that the specificity and
sensitivity are: 76.5% and 70.5% for the front view and 88.2% and
54.5% for the back view, respectively. The current assessment of the
content of information in the IR-images seems to display distinctive
features between DFD patients and controls free from DFD.
