GPU-boosted online image matching

Alexandre Chariot, Renaud Keriven

Abstract: Matching feature points between images is a key point in many computer vision tasks. As the number of images increases, this rapidly becomes a bottleneck. We here present how to use the power of GPUs to obtain image matching in typically 20 ms for one thousand points. This speedup makes applications like interactive image matching possible. Such a portable system, dedicated to 3D large scale reconstruction, is reported.
