Oh, yes please!! We've been crying out loud about this for ages, but there seemed to be next to nil community support in the form of close votes/flags/downvotes. From What should happen to DSP questions that have several answers/an accepted answer on SO already?: Ideally, algorithms, ideas and approaches should be first and foremost and not code in ...

We try and filter out MATLAB-only questions. Most of them either get closed (if they're not that great) or migrated to Stack Overflow (if they're good but off topic). If you feel like a question is more about MATLAB than about signal processing, you should flag it and we'll definitely take a look at it.

Just my opinion: With one exception, I think they belong here. The exception is when it gets into hardware implementation of PID loops: if it involves a discussion of op-amps, RC values, A/D or D/A converters, I'd send the question over to electronics.stackexchange.com

Yes, both analog and digital controls questions are welcome here.

We already have @stacksignals on Twitter.

Definitely! There has been some discussion in the teacher's lounge (all-mod chat room) about this: there is zero information available to mods from other SE sites to say what is on-topic for SP.SE. A suggested update: What topics can I ask about here? Signal processing conceptual questions. Example: Why is the Fourier transform so important? Signal ...

Provided you haven't asked the question on a different SE forum, feel free to ask it here. We have several OpenCV questions here. Just try to ascertain whether it's really a programming question, rather than one related to image processing. Calibration questions (even using OpenCV) are on-topic; questions about which function to use... perhaps not so much.

That's a great point! I'll put up an announcement for a Meta discussion about that later today.

There are some numerical analysis method which are specific to DSP/image processing & computer vision . For example fractional optimization which is ubiquitous in bundle adjustment and 3D reconstruction, robust statistics and some other. Compressed sensing while being almost pure numerical even sounding like DSP and used mostly in DSP/vision. In those ...

Should we ask for a move? Yes, I would second that request although, I would not get too caught up with labels. The whole "Data Science", "Network Science" and other terms, are sitting a bit oddly with my understanding. What else does anyone expect a scientist to do other than work with data? So, independently of whether "we" are scientists or DSP can be ...

Since I was the one who closed the referenced question, I'll answer for that specific question and then try to generalize. For that specific question, I believe there are many possible answers, none of which are "technically" correct and all of which are a matter of opinion. For example: Removable Discontinuity : I don't personally think this is correct, ...

The question seems more about GIS and/or file formats than signal processing. I'd suggest leaving the question on GIS for a bit longer and see who responds.
