The length and direction of vectors show the relative contribution of each taxa to the first discriminant function. Only the top 15 contributors to each function are illustrated. Full size image A comparison of river and two-spined blackfish gut contents revealed significantly different prey ...
I believe if you're willing to apply the approach to every possible orientation and to negative versions, a good start to image recognition (with good reliability) is to use eigenfaces:http://en.wikipedia.org/wiki/Eigenface Another idea would be to transform both images into vectors of their...
