Improved Boundary and Silhouette Enhancement in Volume Illustration Qianqian Han, Yang Gao, Jizhou Sun, Jiawan Zhang Visualization and Image Processing Group, SRDC, School of Electronic and Information Engineering, Tianjin University, 300072, China hanqianqian@, gaoyang8054@163.com, jzsun@ , jwzhang@ weight silhouette enhancement, are proposed in this Abstract paper. In these two methods, enhancing parameters are varying based on the sample position and gradient Structure cues are the dominant information in a magnitude, instead of keeping constant in rendering rendered image. And conveying structure accurately process. As a result, the amount of enhancement and automatically is a problem still not fully solved in changes in accordance with the volume structure. And volume rendering. The presence of volume illustration the result image is more “properly” enhanced, which allows a more flexible way in conveying structure clearly conveys data structure, and keeps detailed information compared with the traditional transfer information at the same time. In addition, due to the function. This paper presents two improved approaches parameters’ variability according to data structure,
