Abstract

In certain embodiments, a system, a computer-implemented method, and computer-readable medium are disclosed for enhanced ophthalmic visualization. A plurality of images corresponding to different portions of the electromagnetic spectrum are obtained and combined, such as by pixel-wise subtraction to obtain a combined image. The images may be weighted with weights selected to enhance visualization of features, such as layers of the retina or features corresponding to pathologies. The combined image may be processed, such as by a machine learning model, to extract features.
