摘　　要：现有的视觉传达系统中,图形元素融合效果不佳,且耗时较长。为此,提出一种视觉传达系统平面图形元素多维化融合方法。设计视觉传达系统框架,对系统中图形元素融合部分做出具体分析。采用SIFT特征描述子提取平面图形元素多维特征;通过计算特征点对的转换矩阵,完成图形元素特征配准;配准后,基于窗口的方法,将图形元素划分为不同的能量区域,选取出能量最大的区域,将该区域像素作为待融合图形元素像素值,实现融合处理。实验结果表明,所提方法具有较好的图形元素融合效果,且相较于其他方法,融合耗时较短。As the fusion effect of graphic elements in the existing visual communication system is unsatisfactory and it takes a long time,a multi⁃dimensional fusion method of plane graphic elements in visual communication system is proposed.The framework of visual communication system is designed,and the fusion part of graphic elements in the system is analyzed concretely.The multi⁃dimensional features of plane graphic elements are extracted by means of SIFT feature descriptor,and the transformation matrix of feature point pairs is calculated to complete the feature registration of graphic elements.After registration,the graphic elements are divided into different energy regions based on window method,from which the regions with the largest energy are selected,and the pixels in this region are taken as the pixel values of the graphic elements to be fused,so as to realize the fusion processing.The experimental results show that the proposed method has better fusion effect of graphic elements,and the fusion time is shorter than that of other methods.
