this paper presents a new procedure for automatic extraction of the blood vessels and optic disk (od) in fundus fluorescein angiogram (ffa). in order to extract blood vessel centerlines, the algorithm of vessel extraction starts with the analysis of directional images resulting from sub‑bands of fast discrete curvelet transform (fdct) in the similar directions and different scales. for this pur...

Automatic generation of kidney regions of interest for radionuclide renograms is possible by defining a reference image and reference regions, using a non-linear image registration algorithm to map a totalised image from a patient to the reference image and using the mapping produced to map the predefined reference regions back onto the patient image. The accuracy of the automatically derived r...

We have developed a semi automatic image segmentation tool which combines con ventional manual segmentation utilities with a novel automatic image segmentation algorithm Manual segmentation is achieved by dropping control points and tting cu bic splines to these points Automatic segmentation is achieved by bimodally thresh olding local windows of the target image and contour following By combin...

We are under the illusion that seeing is effortless, but frequently the visual system is lazy and makes us believe that we understand something when in fact we don’t. Labeling a picture forces us to become aware of the difficulties underlying scene understanding. Suddenly, the act of seeing is not effortless anymore. We have to make an effort in order to understand parts of the picture that we ...
