Enhancement and bias removal of optical coherence tomography images: An iterative approach with adaptive bilateral filtering
Optical coherence tomography (OCT) has continually evolved and expanded as one of the
most valuable routine tests in ophthalmology. However, noise (speckle) in the acquired
images causes quality degradation of OCT images and makes it difficult to analyze the
acquired images. In this paper, an iterative approach based on bilateral filtering is proposed
for speckle reduction in multiframe OCT data. Gamma noise model is assumed for the
observed OCT image. First, the adaptive version of the conventional bilateral filter is applied …
