Image interpolation1
Image Interpolation

  • Sampled Image:

  • Reconstructed image by interpolation:


Image interpolation2
Image Interpolation

  • Separable Interpolation Kernels

  • Shannon Kernel

  • For band limited signals, according to Nyquist we can get a perfect reconstruction


Image interpolation3
Image Interpolation

  • Separable Interpolation Kernels

  • Pixel Replication


Image interpolation4
Image Interpolation

  • Separable Interpolation Kernels

  • Bilinear Interpolation
