I am using strongest SURFfeatures to identify geese (several hundred per image) in aerial photos. Is there a way to acquire the centroid for each of the clustered SURFfeatures around geese? I want to crop images of geese for BagOfFeatures analysis.

You need an unsupervised cluster analysis to tell you how many clusters (geese) there are. See http://www.mathworks.com/help/stats/cluster-analysis.html Once you know which cluster each circle belongs to then you can take the average of all the green circle centroids (little green +) to get the overall centroid of all the circles in each goose.
