Abstract
A method segments n-dimensional by first determining prior information from the data. A fidelity term is determined from the prior information, and the data are represented as a graph. A graph Laplacian is determined from the graph from the graph, and a Laplacian spectrum constraint is determined from the graph Laplacian. Then, an objective function is minimized according to the fidelity term and the Laplacian spectrum constraint to identify a segment of target points in the data.
