Temporal coherent image segmentation and its applications Song-Hai Zhang Xian-Ying Li Tao Chen Yi-Fei Zhang Shi-Min Hu Department of Computer Science and Technology Tsinghua University Beijing China Ralph Martin School of Computer Science Informatics Cardi University Wales UK Abstract We propose a trapped-ball method for image segmentation which is fast supports non
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
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
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
Automated Choroidal Segmentation on OCT A brief review of the techniques under investigation JAY CHHABLANI MD A dvances in optical coherence tomography have changed clinical practice over the last two decades with OCT becoming an essential part of the management of macular diseases Recently imaging of the choroid has become possible with the advent of enhanced depth imaging
