An interobject distance measure based on medial axes retrieved from discrete distance maps
Per‐Ola Forsgren, Peter Seideman · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1990
A method that measures the distance between extended objects of nonregular shape is presented. The distance measure is an average of a set of minimal point-to-point distances between the borders of the objects. The set of points is collected with a well-defined criterion based on processing of distance values on a connected medial axis formed between the objects.>
