摘要: The display of three-dimensional angiograms can benefit from the knowledge quantitative shape features such as tangent and curvature centerline vessels. These be obtained a curve-like skeleton representation. If connectivity topology are preserved, if geometrical constraints smoothness centeredness satisfied, it is possible to estimate length, orientation, curvature, torsion. It also required that no part original object left unrepresented. An efficient method for identification components developed. First, suitable representation using voxel coding approach yield connected labeled unit-thick paths. desired estimated smoothed version produced by moving average filter. computational cost linear, order Nobject, total number voxels contained in binary volumetric data. shown robust boundary noise.
