This paper introduce the idea to use different interest point detectors so that each core can work on its own subset independently of the others. However, since the image pairs are the same, the homography will be essentially the same and can therefore be distributed by the process that first finds a solution. This will have an impact on how to implement a parallel version of RANSAC.
As shown in the top image pair, if choosing some specific number of top responses for the detectors we obtain less noisy points compared to require the same total amount of points for just one detector, as shown in the bottom, image pair.
The problem is of course to find several different key point detectors and therefore it is something I have been investigating in several papers.
