    Take a look at Rosenfeld & Kak or Ballard & Brown (or any other reasonable IP book)
    for weights and algorithms.

Another good IP book for this is:

    Pratt, W. K., _Digital Image Processing_, John Wiley & Sons (1978), sect.
      4.3.2: "Interpolation Functions", pp. 113-116.

In addition, the following paper is a good comparision of the results of several
interpolation weigting functions.  In addition it gives a cubic spline
interpolation weighting function not usually discussed in textbooks (i.e. it is
*not* the traditional cubic B-spline) which gives good results with medicalCT
and MRI images:

    Parker, J. A., R. V. Kenyon, and Troxel, D. E., "Comparison of Interpolating
      Methods for Image Resampling", _IEEE Transations on Medical Systems_, Vol.
      MI-2, No. 1, March, 1983, pp. 31-39.
