RT Conference_Proceedings T1 Multi-GPU registration of high-resolution multispectral images using HSI-KAZE in a cluster system A1 Ordóñez Iglesias, Álvaro A1 Blanco Heras, Dora A1 Argüello Pedreira, Francisco K1 MPI K1 GPU K1 CUDA K1 Multispectral K1 Image registration AB Feature-based registration methods have been demonstrated to be very effective to register multispectral images with large distortions or transformations despite the higher execution time that they require. In this paper, a first approach to a multi-node, multi-GPU implementation of the Hyperspectral KAZE (HSI-KAZE) method for co-registering bands and multispectral images is presented. Different multispectral datasets are distributed among the available nodes of a cluster using MPI and exploiting the parallel stream-based capabilities of the GPUs inside each node using CUDA.
