Interpretation of uniform translational image motion: DCT versus FT
We study properties of the discrete cosine transform (DCT) when applied to an image sequence formed by uniformly translating a still image. The Fourier transform (FT) applied to s...

Medical image registration using Phase-Only Correlation for distorted dental radiographs
This paper proposes an efficient dental radiograph registration algorithm using Phase-Only Correlation (POC). The use of phase components in 2D (twodimensional) discrete Fourier t...
