Abstract

This paper proposes new computational strategies to improve optical coherence tomography image quality for age-related macular degeneration identification. Integrated into an age-related macular degeneration detection system, these algorithms automate and improve the identification of abnormalities in optical coherence tomography images, aiding in the classification of normal and abnormal macular tissues. The research presents an innovative approach to detecting age-related macular degeneration related anomalies, combining texture analysis, statistical evaluation, and genetic algorithms for feature selection. Genetic algorithm optimization finds the best predictive characteristics by using in-depth texture analysis with the gray level co-occurrence matrix and comprehensive statistical research. Gray level co-occurrence matrix features are analyzed at four angles (0°, 45°, 90°, and 135°), with the random forest classifier trained using optimized features. The random forest classifier plays a vital role in both the training and testing phases, achieving no-table results: an error rate of 0% for selected features, 1.9% for all features, and 7.5% for no features, and an overall system classification accuracy of 100% for training data for all, while maintaining 92.458% 98.113%, 100% for testing data of no features, all features and selected features.

基于灰度共现矩阵特征、遗传算法和随机森林分类器的光学相干断层图像年龄相关性黄斑变性诊断。
本文提出了一种新的计算策略,以提高光学相干断层扫描图像质量,用于年龄相关性黄斑变性的识别。将这些算法集成到与年龄相关的黄斑变性检测系统中,自动化并改进了光学相干断层扫描图像中异常的识别,有助于对正常和异常黄斑组织进行分类。该研究提出了一种结合纹理分析、统计评估和遗传算法进行特征选择的创新方法来检测与年龄相关的黄斑变性相关异常。遗传算法优化通过对灰度共生矩阵进行深度纹理分析和综合统计研究,找到最佳的预测特征。从4个角度(0°、45°、90°和135°)分析灰度共现矩阵特征,使用优化后的特征训练随机森林分类器。随机森林分类器在训练和测试阶段都发挥了至关重要的作用,实现了无表结果:对所选特征的错误率为0%,对所有特征的错误率为1.9%,对无特征的错误率为7.5%,对所有训练数据的总体系统分类准确率为100%,而对无特征、所有特征和所选特征的测试数据的分类准确率为92.458% 98.113%,100%。

期刊介绍: Technology and Health Care is intended to serve as a forum for the presentation of original articles and technical notes, observing rigorous scientific standards. Furthermore, upon invitation, reviews, tutorials, discussion papers and minisymposia are featured. The main focus of THC is related to the overlapping areas of engineering and medicine. The following types of contributions are considered: 1.Original articles: New concepts, procedures and devices associated with the use of technology in medical research and clinical practice are presented to a readership with a widespread background in engineering and/or medicine. In particular, the clinical benefit deriving from the application of engineering methods and devices in clinical medicine should be demonstrated. Typically, full length original contributions have a length of 4000 words, thereby taking duly into account figures and tables. 2.Technical Notes and Short Communications: Technical Notes relate to novel technical developments with relevance for clinical medicine. In Short Communications, clinical applications are shortly described. 3.Both Technical Notes and Short Communications typically have a length of 1500 words. Reviews and Tutorials (upon invitation only): Tutorial and educational articles for persons with a primarily medical background on principles of engineering with particular significance for biomedical applications and vice versa are presented. The Editorial Board is responsible for the selection of topics. 4.Minisymposia (upon invitation only): Under the leadership of a Special Editor, controversial or important issues relating to health care are highlighted and discussed by various authors. 5.Letters to the Editors: Discussions or short statements (not indexed).
