Median-rational hybrid filters for image restoration
image (very few research reports about tracing eye-fundus blood vessels have appeared in the literature). Fig. 4 is the result of this tracing. Three blood vessels were tested, of which the trace starting points are labelled as A, B and C. When Figs. 3 and 4 are compared, the traced lines look fairly good. The crosses near D and G were processed :juccessfully, but the branches near E and F were...
متن کاملINTERNAL REPORT (Limited Distribution) International Atomic Energy Agency and United Nations Educational Scientific and Cultural Organization INTERNATIONAL CENTRE FOR THEORETICAL PHYSICS TRACING A PLANAR ALGEBRAIC CURVE
In this paper, an algorithm that determines a real algebraic curve is outlined. Its basic step is to divide the plane into subdomains that include only simple branches of the algebraic curve without singular points. Each of the branches is then stably and efficiently traced in the particular subdomain. Except for the tracing, the algorithm requires only a couple of simple operations on polynomi...
متن کاملA Contour Tracing Algorithm that Avoids Duplicate Tracing Common Boundaries between Regions
The authors of this paper have developed a series of techniques on automatic function approximation of raster images, including references [3] and [5] that were published in this journal. In our techniques, contours are traced and their shapes are approximated by a combination of functions including straight line, arc, and quadratic curve. Because our previous works targeted mainly bi...
متن کامل5 Local Parametrization of Space Curves at Singular Points
We propose a symbolic computation algorithm for computing local parametrization of analytic branches and real analytic branches of a curve in n-dimensional space, which is de ned by implicit polynomial equations. The algorithm can be used in space curve tracing near a singular point, as an alternative to symbolic computations based on resolutions of singularities.
متن کاملRight Coronary Artery - Looped, Astray and Muzzled: A case report
Results During the exposure of RCA, the right AVG was found unoccupied. Further probing did reveal the atrial branches bearing a proximal origin, but no ventricular branches in the right AVG. On tracing the atrial branches to their origin, the RCA was visible. The RCA had a normal origin from the right aortic sinus. Soon after, instead of being submerged in the adipose tissue, it produced a uni...
