目的设计并应用将中国可视人数据集中的图片转换为矢量图的算法。方法设计一个算法,并按照此算法设计一个特定的程序,此程序的输出文件格式为ScalableVectorGraphicsSVG,并在轮廓和色彩上比较原来位图和转换后的图形。结果该算法可以对分割后图像进行理想效果的转化,对色彩梯度大的图像,该算法的复杂度会增加。结论该图像格式可以作为一个交换数据存在,对分割后图像有理想的转化效果。在现阶段各种可视化程序的分割机制不同有各种不同的中间文件格式,实施SVG格式标准有助于规范异构可视化平台的数据统一性。

Objective To design and implement a new algorithm to transform the images of Chinese visual humandataset to vector graphics. Methods A program was developed for the images transformation by using the designedalgorithm. The output file of the program is a vector graphics format of scalable vector graphics (SVG), and it couldcompare the original bitmap with the graphics after transformation according to its profile and color. Results Thedecisive quality image was achieved by adjusting the parameters of the algorithm. The more the color gradient becomes,the harder the calculation will be. Conclusion The implements of transforming the bitmap images could facilitate resolvingthe problem of the interactive format of kinds of platform data of three dimension construction system and to make it moreuniform and standardized.
