| Abstract: | Considering the image problems of the frequency domain volume rendering, a new frequency domain volume rendering algorithm based on data difference is advanced to improve rendering image quality. The data difference set is adopted to supersede original data field. The algorithm calculates the dynamic adjustor of 3D data field to adjust the image quality dynamically by simulating and compensating the realistic effect and depth effect of the rendering image. Sampling voxel combination and other techniques are adopted to speed up rendering process. Experimental results show that the algorithm can improve image quality and the speed of rendering process. |
