Detection of neovascularization in the optic disc using an AM-FM representation, granulometry, and vessel segmentation
2012
2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society
Preserved Fulltext
Textural features extracted by using amplitude-modulation frequency-modulation (AM-FM) techniques and granulometry are used to differentiate NVD from a normal optic disc. ...
Neovascularization on the disc (NVD) is diagnosed when new vessels are located within one disc-diameter of the optic disc. Accurately detecting NVD is important in preventing vision loss due to DR. ...
By combining the bottom-up vessel segmentation approach and extracting textural features with AM-FM and granulometry, good performance results were obtained in the classification of NVD. ...

This paper presents a multiscale method to detect neovascularization in the optic disc (NVD) using fundus images. ...
All the vessels in the ROI are segmented by adaptively combining contrast enhancement methods with a vessel segmentation technique. ...
We also thank The University of Texas Health Sciences Center in San Antonio and the Retina Institute of South Texas for providing our dataset. ...

Agurto et al. applied AM-FM Representation and Granulometry to extract features (AM-FM types of features) and vessel segmentation on ROI by adaptive vessel segmentation (consecutive level for enhancement ...
Of all the 15 features of proliferative retinopathy, new vessels at the optic disc can be detected [7] . This approach is not useful for new vessels outside of the optic disc area (NVE). ...
