最近两位计算机科学的研究人员已经提出了一个算法，这个算法能用于提取出像素图形的低分辨率部分，提升其分辨率准确地适合向量图形。
A pair of computer science researchers have come up with an algorithm that can take a low-resolution piece of pixel art and upscale it accurately to vector graphics.
第一项任务(也是最重要的任务)是计算图形的比例因子，就是说在绘图时每单位的值在高度上要占用多少像素。
The first (and most important) task is to calculate the scaling factor for the graph. This is simply how many pixels in height each value will be worth when it is plotted.
