Is there anyway to extract dense sift/surf features with opencv.

With dense I mean, that in a regular grid of some size, compute features at each vertex.

as long as you are using the 2.4 branch, you can use the GridadaptedFeatureDetector

or create a grid version of any keypoint detector like this:

Ptr<FeatureDetector> pfd = FeatureDetector::create("GridORB");
