Hi All,
I'm working on coding some 2-D interpolation techniques. With wikikepdia's help, I've managed blinear interpolation.
What other techniques are out there? Please tell me a little about how your favourite technique works.
I've read about higher order methods, using more surrounding points, but can't get that to work. I've had no trouble extracting the 16 corners of the 3x3 grid my desired point is in form my data set, but how do I get down from 16 points to one? Using google everyone is talking about image processing, rather than the more basic task of interpolating to a number - of course images are just numbers - but I can't find the basic equations.
Thanks in advance for any help,
