I think you are talking about something like this? Moving Least Squares or Thin Plate Splines

also here some code for opencv http://ipwithopencv.blogspot.com/2010/01/thin-plate-spline-example.html http://ipwithopencv.googlecode.com/svn/trunk/ http://code.google.com/p/imgwarp-opencv/

I think you can generate some map and then use remap.

How it can be done for android?

I don't work with android, but I think you can build OpenCV for android and then just use code for OpenCV.

I did not find a class or package which contians Thin-plate spline effect. Do you know where it hides? :-)

You will not find a package whick contains "Thin-plate spline effect", but you will find one with remap and some image transformations. Do not expect opencv to have functions to apply all kinds of pre-defined image effects. Opencv is more generic and provides functions for you to build your own custom effects.
