Research on Mesh Smoothing Algorithm Based on Vascular Model
Three-dimensional vascular model is an important auxiliary reference for the diagnosis of cardiovascular diseases,but the surface noise will have a certain impact on the diagnosis,and grid smoothing is needed.According to existing mesh smoothing algorithms,it is still challenging to retain clear features and reduce volume shrinkage.Therefore,a combinatorial smoothing algorithm is proposed in this paper,and it is applied to the three-dimensional models of different human tissue structures for verification.The results show that the algorithm can a-chieve noise removal,feature preservation and shrinkage reduction by combining surface reconstruction and bilater-al filtering.
