Medical Image Registration Using B-Spline Transform

Hierarchical B-spline has been widely used for shape modeling in many fields. Registration result is achieved by minimizing a cost function which represents the cost associated with the image similarity. In this paper we present an application of this concept in the form of free-form deformation with a newly proposed metric. This new metric combines the mean square metric and the distance of bo...

Tetrahedral Interpolation for Deformable Image Registration on GPUs

We speed up the tetrahedral interpolation step of a deformable image registration code called MORFEUS. We implement several versions of the interpolation code on a Fermi GPU (GTX480). Despite the irregularity of the code, we obtained kernel speedups of up to 24.6x, 33.7x and 62.4x on three real-life benchmarks. These numbers do not include the data transfer time between the CPU and the GPU beca...

Efficient Cubic B-spline Image Interpolation on a GPU

Application of geometric transformation to images requires an interpolation step. When applied to image rotation, the presently most e cient GPU implementation for the cubic spline image interpolation still cost about 10 times as much as linear interpolation. This implementation involves two steps: a pre lter step performs a two-pass forward-backward recursive lter, then a cubic polynomial inte...

B-LUT: Fast and low memory B-spline image interpolation

We propose a fast alternative to B-splines in image processing based on an approximate calculation using precomputed B-spline weights. During B-spline indirect transformation, these weights are efficiently retrieved in a nearest-neighbor fashion from a look-up table, greatly reducing overall computation time. Depending on the application, calculating a B-spline using a look-up table, called B-L...
