摘要：
It is difficult to employ the elastic registration technique in real time application due to its computation cost. With user-friendly programmability and parallel computation, contemporary graphics processing units (GPU) provide a new strategy to solve the problem above. Based on the characteristics of GPU, a platform was proposed to deal with elastic registration using thin-plate spline as the transformation model. Experiments for 2D registration of monomodal and multimodal images were performed. Results show that by using GPU transformation can be obtained more rapidly than by CPU. Particularly, the processing speed of GPU is higher than that of CPU by over one order of magnitude when dealing with images of large size and high resolution.
