Bilinear Gaussian Lanczos? Downsampling!Mar 17, 2006 · 1 minute read · Comments
Not easy to choose a downsampling algorithm. Some links:
- mplayer: advises bilinear for quality and describes artifacts for each algo
- a blogger: advises lanczos. This links shows pictures produced by each algo.
- digital image interpolation: seems to have a preference for bicubic, what photoshop uses.
- videohelp: tested various algorithms and think Bicubic spline is the best.
