The diagnostic of pathological states using thermal images rely in quantitative simple indicators such as thermal symmetry values. It is aim of this research to investigate whether the thermal symmetry definition is enough to discriminate between healthy and pathological states and overlook other statistical methods in that task. Four images of ankles (1 healthy and 3 pathological) were used as data, 2 ROI were analysed. This research proves that the use of thermal symmetry is a poor indicator, boxplot charts and asymmetry coefficients add useful information that must be considered but are insufficient. Further research is required to overcome this.
