【摘要】 本文分析了以草图输入为检索条件的二维矢量图形图档检索时影响查询效果的三种图形图档间的视觉模糊性。在此基础上提出了一种以最小包围面积单元为基础的包含空间关系的层次模型,并以此模型作为草图和矢量图形图档之间的统一表示模型。最后给出了该模型的构造算法。实验结果表明,与传统的基于分解后的基本图元为结点的SRG图表示模型相比,该模型能更加清晰的表达图形图档中的视觉概念。
【Abstract】 This essay analyzes the impact of query results between the three kinds of graphic visual ambiguity in the Sketchbased 2D vector graphics document retrieval.On this basis,presents a surrounding area of the smallest cell-based hierarchical model with spatial relations.And this model can be used as the uniform representation model between the vector graphics document and sketch document.Finally,the model construction algorithm is given.Experimental results show that compared with the traditional SRG graph representation model,our model can more clearly express the concept of visual graphics in the document.
