我们提出了Ardeco,一个新的算法的图像抽象和转换从位图图像到矢量图形。给定一个位图图像,我们的算法自动计算最接近图像的矢量基元和梯度集。此外,可以在用户选择的重要区域中生成更多的细节,这些区域是从眼睛跟踪数据或从用户绘制的重要性地图定义的。我们的算法是基于一个新的两级变分参数分割算法,最大限度地减少芒福德和沙阿的能量和操作的中间三角剖分,以及适应的图像的功能。
We present Ardeco, a new algorithm for image abstraction and conversion from bitmap images into vector graphics. Given a bitmap image, our algorithm automatically computes the set of vector primitives and gradients that best approximates the image. In addition, more details can be generated in user-selected important regions, defined from eye-tracking data or from an importance map painted by the user. Our algorithm is based on a new two-level variational parametric segmentation algorithm, minimizing Mumford and Shah's energy and operating on an intermediate triangulation, well adapted to the features of the image.
