OCT layer segmentation

The abundance of publications in OCT layer segmentation of the retina in the last years shows a big interest in furthering this field With the advent of deep learning big improvements have been achieved in terms of performance especially in pathological cases (AMD DME etc ) replacing the state of the art of graph-based methods The latter cannot deal with highly degenerate retinal layers

Automated segmentation and enhancement of optical

Optical coherence tomography (OCT) is a non-invasive optical imaging method that has proven useful in various fields such as ophthalmology dermatology and neuroscience In ophthalmology significant progress has been made in retinal layer segmentation and enhancement of OCT images There are also segmentation algorithms to separate epidermal and dermal layers in OCT-acquired images of human

Automatic and robust segmentation of endoscopic OCT

We report a generic method for automatic segmentation of endoscopic optical coherence tomography (OCT) images In this method OCT images are first processed with L 1-L 0 norm minimization based de-noising and smoothing algorithms to increase the signal-to-noise ratio (SNR) and enhance the contrast between adjacent layers The smoothed images are then formulated into cost graphs based on their
