Deep Learning for Diagonal Earlobe Crease Detection
This work addresses a specific medical imaging challenge for healthcare applications, but it is incremental as it applies existing deep learning methods to a new dataset.
The paper tackled the problem of detecting diagonal earlobe crease (DELC), a potential marker for heart attacks, by creating the first public dataset and evaluating deep learning models, achieving 97.7% accuracy with a pre-trained encoder and customized classifier.
An article published on Medical News Today in June 2022 presented a fundamental question in its title: Can an earlobe crease predict heart attacks? The author explained that end arteries supply the heart and ears. In other words, if they lose blood supply, no other arteries can take over, resulting in tissue damage. Consequently, some earlobes have a diagonal crease, line, or deep fold that resembles a wrinkle. In this paper, we take a step toward detecting this specific marker, commonly known as DELC or Frank's Sign. For this reason, we have made the first DELC dataset available to the public. In addition, we have investigated the performance of numerous cutting-edge backbones on annotated photos. Experimentally, we demonstrate that it is possible to solve this challenge by combining pre-trained encoders with a customized classifier to achieve 97.7% accuracy. Moreover, we have analyzed the backbone trade-off between performance and size, estimating MobileNet as the most promising encoder.
