手绘草图既是设计的自然也是至关重要的部分，但目前的设计自动化软件不支持手绘草图。我们正在努力将纸和铅笔的灵活性和易用性与计算机的处理能力结合起来，以创造一个感觉像纸一样自然但更智能的设计环境。实现这一点的最基本步骤之一是使用特征点检测和近似将草图中原始的数字化笔画转换为预期的几何对象。我们演示了如何将多个信息源组合在一起进行笔画特征检测，并使用两种方法来应用这一技术，一种是使用简单的基于平均的阈值处理，另一种是使用尺度空间。论文导师：兰德尔·戴维斯题目：电气工程与计算机科学系
Freehand sketching is both a natural and crucial part of design, yet is unsupported by current design automation software. We are working to combine the flexibility and ease of use of paper and pencil with the processing power of a computer to produce a design environment that feels as natural as paper, yet is considerably smarter. One of the most basic steps in accomplishing this is converting the original digitized pen strokes in the sketch into the intended geometric objects using feature point detection and approximation. We demonstrate how multiple sources of information can be combined for feature detection in strokes and apply this technique using two approaches to signal processing, one using simple average based thresholding and a second using scale space.
