Great job, its surely interesting!

One question (as I am currently interested-in/working/researching-on a 
specific class of interpolation filters) about this comment on the page:

   "To find the best filtration function I used simple numeric methods. 
  I represent searched function as SPLINE. Than I run program, witch 
  change spline points, to get minimal error."

To my understanding the sinc function can be interpreted as a spline, so 
if you explicitly represent the searched function as spline, it is 
naturally the most powerful spline that fits it best.  Do I misinterpret 
your statement?  (I will take a look at your source code tomorrow).
