Medical imaging mainly treats and processes missing, ambiguous , complementary, redundant and distorted data. Biomedical image registration is the process of geometric overlaying or alignment of two or more 2D/3D images of the same scene, taken at different time slots, from different angles, and/or by different acquisition systems. In medical practice, it(More)
Image Registration (IR) is an optimization problem computing optimal parameters of a geometric transform used to overlay one or more source images to a given model by maximizing a similarity measure. In this paper the use of bio-inspired optimization algorithms in image registration is analyzed. Results obtained by means of three different algorithms are(More)
The most osteophyl cancer diagnosed amongst women is breast cancer. It's incidence depends on antecedents, on race, on environment, medication and life quality, but it is arising to all ages and it is not forgiving patient ignorance. Easy, non-harmful ways of cancer detection implemented nowadays, became more accessible for all the possible subjects. The(More)

Presented are the methods proposed by authors to identify and model the optic disc in colour retinal images. The first three our approaches localized the optic disc in two steps: a) in the green component of RGB image the optic disc area is detected based on texture indicators and pixel intensity variance analysis; b) on the segmented area the optic disc(More)
