چکیده

Background: Arcus Senilis (AS) appears as a white, grey or blue ring or arc in front of the periphery of the iris, and is a symptom of abnormally high cholesterol in patients under ۵۰ years old. Objective: This work proposes a deep learning approach to automatic recognition of AS in eye images.Material and Methods: In this analytical study, a dataset of ۱۹۱ eye images (۱۳۰ normal, ۶۱ with AS) was employed where ¾ of the data were used for training the proposed model and ¼ of the data were used for test, using a ۴-fold cross-validation. Due to the limited amount of training data, transfer learning was conducted with AlexNet as the pretrained network. Results: The proposed model achieved an accuracy of ۱۰۰% in classifying the eye images into normal and AS categories. Conclusion: The excellent performance of the proposed model despite limited training set, demonstrate the efficacy of deep transfer learning in AS recognition in eye images. The proposed approach is preferred to previous methods for AS recognition, as it eliminates cumbersome segmentation and feature engineering processes.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
