Choosing how to choose keypoints - SIFT, SURF and HARRIS

OTB Features multiple keypoint detectors for image matching purposes. I have talked about SIFT and SURF in before, I recently added the simpler Harris to the disparity map plugin. All 3 work to some extent, Harris manages to produce thousands of keypoints with default parameters and cause memory errors. Something I will definitely have to fix.

Otherwise the long awaited graphical filter connector plugin should be the one I will work on next. I have enough single plugin blocks to make a chaining tool useful. Leave me some notes on which elements you would like to see in it.
