Cam Q. T. Thanh, Nguyễn Thanh Hải · American Journal of Signal Processing · 2017
Medical image processing to support doctors for exact diagnosis and early treatment plays an important role. In this paper, construction of a three-dimensional (3D) image from 2DMRI cortex images is proposed. In addition, the 3D image may represent the visual details of brain inside human cortex. The 2DMRI cortex images are pre-processed using the mean filer for removing multiplicative noises and the histogram equalization for enhancement is applied. In addition, the multilevel Otsu method is employed to separate brain part inside the human cortex and a proposed algorithm of the trilinear interpolation is utilized for the construction of a 3D image. Simulation results show that the effectiveness of the proposed approach and also it is a sharing information for developments of 3D image construction.
