If anyone knows how to automate the final step of actually making the plot, please let me know or post your own answer.

comment Stitch edge of disk to edge of square in 3D space (with deformations)
@djp: Given the example of paper cutouts, I assume that the deformation is meant to be isometric. See also: dForm

comment How to enhance a fuzzy image
A disk is a better model for defocus blur than a Gaussian function. Set r = 6; k = DiskMatrix[r]/Total[DiskMatrix[r], Infinity]; and try ImageDeconvolve[image, k, Method -> "RichardsonLucy"] or ImageDeconvolve[image, k, Method -> {"TotalVariation", "NoiseModel" -> "Laplacian"}]. The results aren't super fantastic, but they're something.

comment How to enhance a fuzzy image
Blurring is a form of convolution. To undo it, what you want is deconvolution, i.e. ImageDeconvolve. However, your image also has a lot of noise, which makes deconvolution very hard.

You'll have better luck if you make your control polygon have three-fold symmetry.

comment How to generate mesh and calculate volume of 3d object?
Sorry, maybe there's something I'm missing, but why can't you just keep using your NIntegrate[ρ^2 Sin[θ], ...] method?
