Multimodal retinal imaging: new strategies for the detection of glaucoma

Glaucoma is a serious worldwide disease whose treatment can be improved by early detection. As part of a new clinical approach this paper introduces some preliminary studies in the computerised detection of the disease. In particular we consider the problems of registering 3D laser data with a digital image. We introduce a new method based on windowed mutual information and show that it performs better than the standard mutual information technique.
