研究目的
Developing a computerized method to identify Macular Edema (ME) at its earlier stages using OCT images.
研究成果
The proposed computerized method can detect and diagnose ME at its earlier stages with a high accuracy rate of 97.5%, aiding ophthalmologists in early treatment.
研究不足
The algorithm was tested on a specific dataset from Heidelberg Engineering Inc., and its applicability to all types of retinal images is not confirmed.
1:Experimental Design and Method Selection:
Utilizes segmentation based fractal texture analysis (SFTA) to derive the feature vector, graph based segmentation for layer detection, and QDA for classification.
2:Sample Selection and Data Sources:
OCT scan results from 45 patients, including 15 healthy results, 15 patients suffering from AMD, and another 15 affected with DME.
3:List of Experimental Equipment and Materials:
OCT images from Heidelberg Engineering Inc.
4:Experimental Procedures and Operational Workflow:
Preprocessing of images, layer detection using graph based algorithm, feature extraction including thickness profile and cyst fluid detection, and classification using QDA.
5:Data Analysis Methods:
Accuracy, sensitivity, and specificity calculations.
