comment Convolution with additional cosine
Be clear here - is $\Theta$ a function of two vectors, or a function of the single vector $\theta - \theta'$?

comment Convolution with additional cosine
I don't see how your comment relates to my answer. If you're doing this numerically, you just need to precalculate $G(x^2 + y^2)\cos(\Theta(x, y))$, and convolve that with H (which from your SO post, I assume is a discrete image)

$\Theta$ is a function too, right?

Convolutions aren't normally done as a double integral - are you sure that shouldn't be $d\theta$ instead of $d^2 \theta$

comment What is the maximum volume of $N$-D slice of an $M$-D hypercube?
Yes, with edge vectors $\begin{bmatrix} 1&1&0&0&0 \end{bmatrix}$ and $\begin{bmatrix} 0&0&1&1&1 \end{bmatrix}$. Sorry @kennytm, counterexample of area $\sqrt 6 \neq \sqrt{5 - 2 + 1}$

Is it possible to pull a $\sqrt 2 \times \sqrt 3 $ rectangle out of a 5-cube?

comment What is the maximum volume of $N$-D slice of an $M$-D hypercube?
@kennytm: That's definitely a lower bound, but I'm not sure it's optimal.
