Non-invasive Diabetes Detection using Gabor Filter: A Comparative Analysis of Different Cameras
This work addresses convenient diabetes screening for patients, but it is incremental as it applies existing methods to new camera types.
The paper tackled non-invasive diabetes detection by comparing mobile and laptop cameras for capturing facial images, achieving up to 96.7% accuracy using SVM on a 12mp camera.
This paper compares and explores the performance of both mobile device camera and laptop camera as convenient tool for capturing images for non-invasive detection of Diabetes Mellitus (DM) using facial block texture features. Participants within age bracket 20 to 79 years old were chosen for the dataset. 12mp and 7mp mobile cameras, and a laptop camera were used to take the photo under normal lighting condition. Extracted facial blocks were classified using k-Nearest Neighbors (k-NN) and Support Vector Machine (SVM). 100 images were captured, preprocessed, filtered using Gabor, and iterated. Performance of the system was measured in terms of accuracy, specificity, and sensitivity. Best performance of 96.7% accuracy, 100% sensitivity, and 93% specificity were achieved from 12mp back camera using SVM with 100 images.
