A Scalable and Efficient Algorithm for Computing the City Block Distance Transform on Reconfigurable Meshes

摘要

The distance transform is a basic operation in computer vision, pattern recognition and robotics. In this paper, we consider the city block (L1) distance metric. An algorithm for computing the city block distance transform on reconfigurable meshes is proposed in this paper. The time complexity and scalability of the algorithm are analysed. The results indicate that the algorithm is scalable and efficient.
