The problem in the constrained setting for image segmentation has been studied by Yu and Shi [21] where they find the solution to the normalized cuts problem sub-ject to a set oflinear constraintsofthe formUTx = 0. This problem can be reduced to an eigenvalue problem which can be solved using spectral techniques as well. Ericks-son et al.
