Signed euclidean distance transform
WebFollowing is a list of several common distance measures to compare multivariate data. We will assume that the attributes are all continuous. Euclidean Distance. Assume that we have measurements \(x_{ik}\), \(i = 1 , \ldots , N\), on variables \(k = 1 , \dots , p\) (also called attributes). The Euclidean distance between the ith and jth objects is WebPerform another distance transform on the new binary image. Observe that the datatype (in particular 8-bit) of the distance transform image limits the distances. Discuss different …
