As the algorithm tries to balance the volume (ie balance the region sizes), if we take circles with different sizes, the segmentation fails. In addition, as there is no useful information in the intensity of the image, or its gradient, we choose to perform the spectral clustering on a graph that is only weakly informed by the gradient.

Spectral clustering for image segmentation. ¶. In this example, an image with connected circles is generated and spectral clustering is used to separate the circles. In these settings, the Spectral clustering approach solves the problem know as ‘normalized graph cuts’: the image is seen as a graph of connected voxels, and the spectral ...
