Digital Fundus Image Stitching for Generation of Retinal Mosaicto Help Ophthalmologists

Abstract

These days medical Imaging is a very important field and is helping doctors in various ways to diagnose diseases and treat them. Fundus image is used by doctors has a limited field of view and to overcome this problem a new technique is presented in this paper to stitch the images together to generate a mosaic image. Proposed methodology uses Weber local descriptor for feature extraction and then a new technique is presented for seamless stitching. A locally gathered database is used and results are compared with other state of the art techniques. Significance of proposed system can be seen from the results generated.
