Generating High-Quality Triangle Meshes from Medical Images
2017
International Journal of Signal Processing, Image Processing and Pattern Recognition
Due to limited resolution factor, triangle meshes extracted from medical CT images often contain staircase artifacts. In order to remove staircase artifacts during mesh generation and obtain a smooth model from medical images, a novel removing staircase artifacts method is presented. Firstly, we extract contours by using image segmentation and convert a stack of contours into point clouds. Estimating the normals of point clouds and discard outliers by a weighted covariance analysis, and then
