New CLAHE pipeline enhances retinal images for improved diagnosis

Researchers have developed a novel two-stage image enhancement pipeline for retinal fundus images, combining luminosity correction with Contrast Limited Adaptive Histogram Equalization (CLAHE). This method specifically targets artifacts like non-uniform illumination and low contrast, which can impede accurate diagnosis of conditions such as diabetic retinopathy and glaucoma. Quantitative validation on the DRIVE dataset demonstrated superior performance over standard Histogram Equalization and Adaptive Histogram Equalization methods, achieving significantly higher scores in PSNR, SSIM, and CNR, with processing times suitable for clinical workflows.
