Inverse filtering to undo a convolution blows up

A better approach would be to apply some method to solve problems on the form $$\min_v \|Mv - d\|$$ or possibly $$\min_v \|M(v+d) - d\|$$ Where $M$ is the Gaussian convolution operation, $d$ is the ...

Confusion over deconvolution cost function gradient

A simple method to derive the above is using the matrix form of the convolution. Since a convolution is a linear operator then it can be expressed using a matrix product: $$ \boldsymbol{h} \ast \...

Inverse filtering to undo a convolution blows up

However, in both cases, the result blows up to infinity when I take the IFFT. The result blows up before that, when you do division by 0: add a small constant to <...
