Paper Abstract

Based on the model of fuzzy function and the distance from objects to lens, a new 3D adaptive stratified filtering of volume image is developed. The volume image is split into several non-intersected sub-level volume images along the z- axis, each sub-level volume image is regard as a 2D image, and processed by 2D filtering. The problems of boundary division and anti-alias are also solved through introducing alpha value. The efficiency of stratified filtering is also improved, and the error of stratified filtering is less than given a constant P. The experimental results show that this is an effective method.
