To become proficient in geometry, students must learn about a variety of lines and angles. One important concept is understanding parallel, perpendicular, and intersecting lines. These lines are basic ...

Abstract: Exploiting geometric features, such as points, straight or curved lines and corners, plays an important role in object recognition. In this paper, we present a model-based recognition of 3D ...

Abstract: The algorithm of line segment intersection is the core algorithm for vector map overlay. The traditional method is based on the plane-sweep process to find the intersections of two groups of ...
