The detection of artery and vein structure is of interest in both medical diagnosis and surgical planning. Here we examine vascular structure in the eye which is important for example to diagnose abnormal vessel growth due to diabetic retinopathy. The results presented here focus on retinal blood vessels; however all methods can be applied to general artery/vein structure.
For example, in future we plan to investigate the three dimensional vascular structure in a human brain.
As the images of interest are large, we ﬁrst use a multi-resolution approach to summarise the image. All inference is then based on the image summarisation rather than the original image. We develop a prior model for vascular structure and use Markov Chain Monte Carlo (MCMC) to sample from the posterior distribution describing the global artery/vein structure in the image.
