A Comparison of Improvements for Shear Warp Algorithm Using Lagrange or Cubic Spline Interpolation
Li Chen, Shaoxiang Hu · 2011
In order to reduce the staircase phenomenon of shear warp, we study how to improve shear warp algorithm base on Lagrange interpolation and Cubic Spline interpolation. Since the staircase phenomenon is caused by not using the deep information along the prime view orientation, a new method is proposed by adding a set of new slices using the adjacent slices in Lagrange interpolation or Cubic Spline interpolation. The experiments demonstrate the powerful of proposed method than linear interpolation.
