Abstract

Weighted distance transforms in volume (3D) images using a voxel grid with equal resolution along two axes and lower along the third are investigated. The weights (neighbour distances) in a local neighbourhood of size 3 x 3 x 3 are optimized by minimizing the maximum error in a cubic image. (C) 2004 Elsevier B.V. All rights reserved.
