In this paper, we present a general and robust algorithm to remesh triangular meshes with genus-0 topology based on their geometric properties. Our algorithm first parameterizes an given original mesh onto planar area, and creates several geometry images for it according to its intrinsic geometric properties, e.g. per-vertex density, per-face normal or texture, etc. Then the algorithm replaces the...
Characteristic of retinal vasculature has been an important indicator for many diseases such as hypertension and diabetes. A digital image analysis system can assist medical experts to make accurate diagnosis in an efficient manner. This paper presents the computer based approach to the automated segmentation of blood vessels in retinal images. The detection of the retinal vessel is achieved by performing...
In this paper, a novel algorithm to synthesize large-scale virtual terrain from a set of images is presented based on digital image processing technologies and radial weighted blending method. The algorithm first creates standardized terrain-blocks from the images, and then smoothes the blocks by employing fast Fourier transform (FFT) and butter worth low-pass filter. A radial-weighted defined on...
