ABSTRACT:
A local image descriptor generation technique that produces a descriptor for an image patch is presented. The technique generally involves smoothing the pixels of the image patch, followed by employing a transformation to produce a transform vector for each of a set of sample points spaced across the image patch. The transform vectors are weighted and spatially accumulated to produce a prescribed number of linearly summed vectors. The linearly summed vectors are concatenated to form a raw local image descriptor, which is normalized to produce a finalized descriptor for the image patch.
