摘要

Three-dimensional reconstruction of wood carving based on CT tomography data is important.In this paper,we propose a novel 3D variational framework for this task,which includes two procedures.First,a fitting approach is applied to a sequence of wood carving images acquired by CT scanner.The regions of interest(ROIs)can be obtained for the second segmentation after fitting.Second,we utilise a 3D TV(total variation)L1 variational model to directly segment the 3D volume of the ROIs.In addition,the TV-L1 model can smooth the volume and gives a clear 3D volume rendering result.By introducing a dual auxiliary variable,the fast primal-dual method is developed to improve the computational efficiency of the 3D TV-L1 model.Extensive experimental results are conducted to demonstrate the performance of the proposed framework.
