Hervella", "José Rouco", "Jorge Novo", "Marcos Ortega" ], "categories": [ "cs.CV" ], "abstract": "The analysis of different image modalities is frequently performed in ophthalmology as they provide complementary information for the diagnosis and follow-up of relevant diseases, like hypertension or diabetes. This work presents an hybrid method for the multimodal registration of color fundus retinography and fluorescein angiography. The proposed method combines a feature-based approach, using domain-specific landmarks, with an intensity-based approach that employs a domain-adapted similarity metric. The methodology was tested on a dataset of 59 image pairs containing both healthy and pathological cases. The results show a satisfactory performance of the proposed combined approach in the multimodal scenario, improving the registration accuracy achieved by the feature-based and the intensity-based methods.", "revisions": [ { "version": "v1", "updated": "2018-03-02T17:07:44.000Z" } ], "analyses": { "keywords": [ "multimodal registration", "domain-specific landmarks", "retinal images", "vessel enhancement", "color fundus retinography" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
