New metric learning approach analyzes retinal images, outperforms neural networks

Researchers have developed a novel metric learning approach using normalized compression distance (NCD) combined with anisotropic structure-enhancing filters to analyze and visualize differences in 3D retinal images. This method aims to overcome limitations of non-metric approaches like neural networks, which can introduce systematic distortions. The NCD-measured structural differences showed a prediction error of approximately 0.5 dB when validated against physician-measured changes in visual field function, outperforming non-metric deep learning methods. Normalized compression vectors (NCV) are proposed as a feature set for measuring visual differences, demonstrated on a glaucoma patient and a non-human primate model. AI

IMPACT This new metric learning approach could lead to more accurate disease diagnosis and monitoring in medical imaging by mitigating distortions common in current deep learning models.
