Lagrange Interpolation for Upsampling
Gwanggil Jeon · International Journal of Multimedia and Ubiquitous Engineering · 2015
In this paper, we compare well known interpolation methods such as nearest neighbor, bilinear, bicubic, triangle kernel, and Lagrangian interpolation method. Reconstruction errors from above interpolation methods are compared using test image. From the simulation results, it can be found that Lagrangian method outperforms all other upsampling methods. Visual performance comparison is provided by using two LC images.
