摘要

Adaptive optics flood-illuminated imaging technology has been successfully used to correct the wavefrontnaberration of human eyes to obtain high-resolution retinal images. However, because of the pollution of variousntypes of noise and the degradation caused by residual aberration, the noisy images are not very clearnand weak edges are difficult to discern. To reveal the abundant detail hidden by large-scale noise and tonenhance low-contrast edges, a hybrid filtering and enhancment method is proposed combining bilateral filtering,ncoherence diffusion, and edge enhancement. Results show that it is effective to improve the visualnquality of retinal cell images. © 2009 Optical Society of America
