چکیده
A variety of multiresolution models for arbitrary triangle meshes have been presented in the last years. In order to achieve an interactive visualization, multiresolution models must store and retrieve data efficiently. In this paper, we present a first step to evaluate and compare multiresolution models. We propose a set of tests to measure the speed performance of the models for interactive visualization and uniform resolution LOD. We have carried out some experiments with implementations of the following two models: Progressive Meshes and Multiresolution Ordered Meshes.

متن کاملContourlet-Based Edge Extraction for Image Registration
Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...
متن کاملAdopting the Multiresolution Wavelet Analysis in Radial Basis Functions to Solve the Perona-Malik Equation
Wavelets and radial basis functions (RBF) have ubiquitously proved very successful to solve different forms of partial differential equations (PDE) using shifted basis functions, and as with the other meshless methods, they have been extensively used in scattered data interpolation. The current paper proposes a framework that successfully reconciles RBF and adaptive wavelet method to solve the ...

متن کاملComparison of hybrid regression and multivariate regression in the regional flood frequency analysis: A case study in Khorasan Razavi province
Background: Magnitude, rate and frequency of the stochastic and unexpected events are of great significance and importance in hydrology. Nowadays, for economic planning of the projects, the use of analytical methods of unexpected events in hydrology is unavoidable. The aim of this study was to compare hybrid regression and multivariate regression to estimate flood peak discharge in the province...
