Abstract

Early screening of the diabetic foot is crucial for diabetic foot prevention and treatment. Since neuropathy and vasculopathy caused by hyperglycemia can lead to abnormal foot temperature, a diabetic foot screening method based on infrared thermography has been recommended. We designed a fully automated method for early screening of the diabetic foot. The automatic segmentation of infrared images of the foot region was achieved by designing an image processing algorithm; the automatic extraction of various temperature features was achieved by combining the angiosome concept. SVM was used to establish a classification model. The study recruited 41 diabetic patients (diabetic group, diabetic foot Wagner grade 0) and 48 healthy individuals (control group) to validate the reliability of the method and showed an accuracy rate of up to 87.5% in the test set.
