Supporting Data and Code: Fast clustering in linear independent 1D subspaces: segmentation of multi-channel images with high spatial resolution To reproduce the results from Table 1. run "SyntheticExperiment.m" script. To reproduce the segementation (except the color coding) from Figure 2. run "RealisticExperiment.m" script. FELRSC algorithm can be run by calling FELRSC.m function.
