基于用户交互的光栅图像局部矢量化方法

A Method of Raster Image Partly Vector Based on User Interaction

该文提出一种基于用户交互的光栅图像局部矢量化的方法。该方法首先将彩色图像处理得到无噪声的二值图像;其次通过用户交互,用边界跟踪方法得到封闭的有序的局部图像轮廓;然后通过基于阈值迭代增加的多边形拟合轮廓方法进行多边形拟合轮廓。通过对新疆维吾尔族服饰花纹的实验,结果表明该方法能有效的减少了轮廓结点个数。最后,将其应用在印花设计中,得到了较好的效果。

This paper proposes a method of raster image partly vectorize based on user interaction.Firstly,it converts color image to noiseless binary image using image processing methods.Secondly it obtains the closed and orderly local image outline by the boundary tracking method after user interaction.Then,using threshold iteration increases polygon fitting outline methods which we proposed to fit polygon contour.The results experimented on decorative pattern on Xinjiang Uygur dress show that the proposed polygon fitting method can effectively reduce the outline node number.Finally,it gets a better effect in printing design.
