@ybeltukov Yes, GaussianFilter (or any other smoothing algorithm; perhaps a wavelet transform) + Spline interpolation would work as well.

comment 2D smoothing spline interpolation
Hi! Perhaps the question or the example code was a bit misleading. I need to obtain a differentiable interpolated and smoothed function from the data. In the test case it should be as close as possible to the original.

The Last time I had to reduce gif size I used gifsicle lcdf.org/gifsicle

Fixing the plotrange might give an even better animation. Still +1

comment Fitting a plane from a set of (x,y,z) values with uncertainties on 3 variables
The weights are for data points see here. As for posting code, we used to have a FAQ, but I can't seem to find it. @belisarius will know.

I guess you would like to use the measured errors as weights for LinearModelFit?

comment How to make a stereogram in Mathematica?
@SimonWoods Yes, I had to reduce the scaling factor before flatten to get better results (but less depth). Reducing the size of the bunny also helped.

comment How to make a stereogram in Mathematica?
I guess something like ImageAdjust@ Rasterize@ DensityPlot[(Sqrt[x^2 + y^2]) ( Cos[6 (Sqrt[x^2 + y^2])] - 0.5), {x, -3, 3}, {y, -3, 3}, Frame -> None, ColorFunction -> GrayLevel, PlotRange -> All] Could work instead of RadialGradientImage

comment How to make a stereogram in Mathematica?
For those of us not yet on V10, could you post a version without RadialGradientImage. I tried using depth = ImageCrop[ ImageAdjust@ Rasterize[ DensityPlot[Cos[x] + Cos[y], {x, 0, 4 Pi}, {y, 0, 4 Pi}, ColorFunction -> GrayLevel, Frame -> False], ImageSize -> {w nx, h ny}], {w nx, h ny}], But all I'm getting are Thread::tdlen: Objects of unequal length in, when running the shift part. (Still +1:)
