And finally last links :

* The myth of infinite detail: Bilinear vs. Bicubic

* Better Image Resizing

<<
After some experimentation, I came up with these rules of thumb:

    * When making an image smaller, use bicubic, which has a natural sharpening effect. You want to emphasize the data that remains in the new, smaller image after discarding all that extra detail from the original image.
  
    * When making an image larger, use bilinear, which has a natural smoothing effect. You want to blend over the interpolated fake detail in the new, larger image that never existed in the original image.

This is why I think we should have a choice of a few algorithms...
