Unsupervised Image Segmentation with Spectral Clustering with R

That title is quite a mouthful. This quarter, I have been reading papers on Spectral Clustering for a reading group. The basic goal of clustering is to find groups of data points that are similar to each other. Also, data points in one group should be dissimilar to data in other clusters. This way you can summarize your data by saying there are a few groups to consider instead of all the points.
