Weighted distance mapping (WDM) [PDF]

IEE International Conference on Visual Information Engineering (VIE 2005), 2005
A new distance mapping technique is introduced: weighted distance mapping (WDM). It is based on an adapted version of Fast Exact Euclidean Distance (FEED) transforms. It computes, after assigning a metric, a probability space for partly categorized or clustered data.
