Popis
Shrnutí:The 3D reconstruction of medical images is a hot spot in medical research. It is a comprehensive application of computer graphics, image processing, computer vision and human-computer interaction. Firstly, in this paper used an improved adaptive weighted median filter algorithm for CT image processing, greatly reduces the amount of data processing, and improve the process effect of the speckle noise and environmental noise. Then the automatic threshold segmentation algorithm and the improved iterative algorithm are used to realize the multi threshold image segmentation. Finally used the marching cubes algorithm and equivalent plane method three dimensional reconstruction of CT image. In this paper through VTK (Visualization Toolkit) and VC++ software to achieve the CT images three-dimensional reconstruction and greatly improve the accuracy and accuracy of medical diagnosis.
