| Summary: | Retinal imaging can effectively diagnose diseases that manifest changes in the retinal anatomy. However, manual diagnosis paradigms are both error-prone and cost-intensive. Therefore, computer-aided technologies were developed for an exhaustive examination of retinal pathology and anatomy. In this article, a new retinal image enhancement method based on fuzzy c-means is proposed to enhance low quality retinal blood vessel images while preserving its brightness. Fuzzy c-means clustering groups the intensity levels into multiple clusters and assigns a cluster membership value to each intensity level. These values are subsequently modified and are then mapped to their corresponding initial values. The green channel of a modified image obtained above is equalized using the adaptive histogram equalization to yield the enhanced image. The results for the proposed algorithm were established using standard datasets consisting of 1000 fundus images with 39 categories. The proposed technique preserves the brightness and improves the contrast while improving vascular segmentation. |
