Though Medial Axis Transform (MAT) is well known for object representation, its use in different kinds of computations remains unexplored till date. One of the main reasons is the popularity of other spatial representations such as Quadtree in 2D and Octree in 3D for better data compression and ordered storage and retreival facility etc. In this paper an algorithm has been proposed for computation of normals at the boundaries of 2D objects based on their Medial Axis Transforms. In this technique, there is no requirement of linking boundary points during the computation compared to other existing techniques. The added advantage in the computation is that the computation can be restricted purely in the integer domain. download full paper
