Feature Based Nonrigid Brain MR Image Registration With Symmetric Alpha Stable Filters

  title={Feature Based Nonrigid Brain MR Image Registration With Symmetric Alpha Stable Filters},
  author={Shu Liao and Albert C. S. Chung},
  journal={IEEE Transactions on Medical Imaging},
A new feature based nonrigid image registration method for magnetic resonance (MR) brain images is presented in this paper. Each image voxel is represented by a rotation invariant feature vector, which is computed by passing the input image volumes through a new bank of symmetric alpha stable (S?S) filters. There are three main contributions presented in this paper. First, this work is motivated by the fact that the frequency spectrums of the brain MR images often exhibit non-Gaussian heavy… CONTINUE READING
