Abstract: We propose an improved algorithm to rapidly set the seaming information in the garment by means of the selected segments in the 3D space. According to our algorithm, the low efficiency brought by previous methods can be improved and the problem of the seaming information’s cluttered display in the 2D background can be solved. Firstly, we build the garment hierarchical model to select the silhouette segments. Secondly, to decrease the human-computer interaction cost and improve the efficiency when setting seaming information, we draw two-dimensional piece’s boundary and determine its border. The relationship between border frame and boundary points is built. Then the seaming information between corresponding boundary points can be set automatically when a pair of border frames is selected. Finally, we show the seaming information in 3D space immediately after setting a pair of seaming correspondence every time to avoid the problem of its cluttered display in 2D background. The experimental results show that the proposed method not only can high up the efficiency of seaming-information setting but also can make the seaming-information be displayed clearer and more intuitively, and then is suitable to set seaming information in different kinds of garments.
