Abstract

Cataract is one of the visual impairments that can lead to blindness if not detected and treated early. Cataract detection still takes a long time and is very objective based on the decision of the ophthalmologist. This is one of the reasons for conducting an automatic screening process based on fundus image analysis. This study was made as decision support for an ophthalmologist in determining whether someone has cataracts or not. There are three main stages in this research, namely preprocessing, feature extraction, and classification. Preprocessing perform by converting the image to grayscale and changing the image size so that the image is easier to process. The second stage is feature extraction by applying Gray Level Co-occurrence Matrix to extract contrast, correlation, energy, and homogeneity features. And the last stage is classification using k-nearest neighbors based on the features that have been obtained from the previous stage. The highest accuracy results obtained are 80% with k = 5, which indicates the proposed method can detect cataracts well.
