A Quadric Error Metrics Based Feature Reserving Simplification Method

This paper presents two edge-collapse based algorithms using improved quadric error metrics.

In order to solve the problem,this paper put forward an improved mesh simplification algorithm based on quadric error metrics.

Multiresolution mesh simplification algorithm with distance-weighted quadric error metric;

Algorithm to generate progressive meshes based on quadric error metric;

This algorithm generalizes the quadric error metric,which is based on the sum of squared distances of the vertex to all the planes in its set,from 3-dimension to n-dimension including attributes information.

This algorithm controls the process of simplification by quadric error and the edge collapse operation is used to simplify meshes.

Based on a quadratic measurement error model,an efficient computational method for estimating the fundamental matrix is presented.
