Looks good, though there might be one piece missing? The "reputation" text color for accepted answers should probably be a little lighter (or different from the current blue). The "answers" one seems to get it right. Just noticed another one: when a question has an accepted answer, the text under the dot showing the number of answers cannot be read.

Well, I probably should have left that as an answer rather than a comment. I tend to just comment if I'm in a hurry and don't have time to compose a more complete answer. Though, for that question, I don't think a more complete answer helps much. Also, I tend to err on staying out of most questions. I prefer the non-mod members answering, so that more ...

I would consider information theory on-topic. The field intertwines with signal processing quite a bit. My only concern is whether or not there are enough frequent visitors that have sufficient expertise in the field to give good answers.

I think we better change the name into Signal and Image Processing. I'm not sure on the URL, But I think I would go with sip.stackexchange.com. The reasoning is simple, many of the questions deals with image-processing, the most popular tag on this site. Yet most of them are by beginners. And why is that? Simple, if you're advanced in the field of Image ...

Yeah, when I saw the main page this morning I felt the same. But honestly I don't think we can do much about that. Potentially we could ask to decrease the amount of questions that are being bumped. On the other hand, during Saturday and Sunday, there were only 5 new questions. Possibly that is also a reason for "Community" to go crazy like that. In ...

I am interested to help out! I was involved in getting the proposal through Area 51, and I want to make the site as useful, interesting and welcoming as possible (within the bounds of the DSP.SE charter).

I guess it could be added, but I'm not sure it needs to be. All signal/image processing aspects of CV are by default on-topic and welcome here. The machine learning and statistics aspect of it might be better served on Stats.SE, although I wouldn't close such a question right away. By the way, computer-vision is our third largest tag. Re: merging of the ...

Noise in the data Let's start with the most obvious thing: we don't have a lot of data. The most discouraging thing about the September evaluation was that the number of evaluators dropped from 7 to 3. The December eval was completed by 4 people. With so few people looking at questions, it's not surprising that voting will be noisy. Since April, there ...

I think sticking to the way things are now is not a bad idea. A good example is the IEEE signal processing society. You got many sub-fields that just fall under the same head denomination, but defined with common technical interests as Technical Committees that focus on various signal processing related activities. Maybe something with the same dsp....

The big problem I have is the large number of questions which seem to have decent answers, but for which the questioner has not awarded a tick.

I don't strongly care about what variable is used to index the signal ($t$ versus $n$ and so on), but I do think it's an important notational distinction to use square brackets when referring to a discrete-time signal. I'm always sure to follow this convention because there's real potential for confusion as to whether a particular signal is defined in ...

Looks great Stéphane! The one thought I have about it (in addition to Peter's suggestion) is that the waveform might benefit from a level of secondary detail to suggest that the signal has been processed. I played around with a few ideas, and this is one that stood out as a possibility: It's mainly to illustrate a style, not necessarily a suggestion to ...

SE.DSP is peer reviewed to some extend. Not in the traditional "journal" sense, meanwhile predatory publishing or randomized peer-review, to name a few, have changed the deal. A post in SE.DSP can sometimes be much more peer-reviewed than a paper in some conferences/journals. However, SE.DSP as a site has no DOI. It can vanish, questions and answers can be ...

Welcome to Helsinki, Finland. I've met with two on-line friends from music-dsp circles. It was great both times, had pizza with the first one (I bicycled to Sweden where we met) and beer with the second one (Norwegian, he had business in Oulu where I lived at the time). EDIT: Users MimSaad (left) and Olli Niemitalo (right) in Oulu, 5 September 2017.

All Stack Exchange sites start out as proposals on Area 51. This site was in proposal state there for over a year. When a site finally collects enough interested users, it moves to Private Beta state, where only users who signed up for the proposal can operate. The site later goes into full Beta, where anyone can contribute. At this point, moderators are ...

The sole IEEE student membership cost about 30$, and the discount on conference fees is generally higher than this amount. The savings can even increase if you are a member of the society the conference belongs. You can receive IEEE Potentials Magazine and IEEE Spectrum Magazine, but the access to IEEExplore requires other subscription fees. So you won't get ... 6 Welcome to West Hartford, Connecticut, USA. Laurent, I'm a dinosaur from the comp.dsp usenet news days (though comp.dsp is still going, I find!). I made several online friends through there, and they've propagated to here, Facebook, and Twitter. A few months ago, I was happy to meet up with two comp.dspers up in Boston (two hours drive from me). One I'd ... 6 I also think it could be fun meeting some SE.DSPers IRL if our space-time paths can be made to intersect with little effort. I can usually be found in the Eindhoven area, the Netherlands. 6 Nanterre, a former central celt city of Gaul, before and close to Paris, France ($\pm\$ 30 kms) SE.DSPeers (the double "e" is on purpose) of all countries unite. I have a network of signal/image processing folks here. And know of a few nice bars and restaurants, with diverse types of foods and drinks.

The short answer is yes - you can and you should answer your own questions. Please read more about it in the FAQ. However, I do not understand what do you mean by "there was no review of any kind"?

This is a well-known problem on the Stack Exchange network, and there are automatic mechanisms in place to try to deal with it. I'm not sure if the process will be triggered by two downvotes, but it may be. Read about it here and here. My advice? Just ignore it. Sure, it's annoying... but is rep on a website really worth more than being happy with the ...

There's also the aspect that questions and answers often have tremendous utility value for others than the original poster. Then it will matter little what the motivations of the original poster were, especially if you believe in something like this quote attributed to Richard Stallman from 1990: When information is generally useful, redistributing it ...

One place to take discussions here on SE.SP is the post-processing chat room. this does require a certain amount of reputation before you can see it and post it. Many of the old-timers here started out on the internet discussing signal processing on the comp.dsp usenet newsgroup. The newsgroup isn't quite what it was in its heyday, but it's still reasonably ...

The removed paragraph was not about answering the question. It was directed at another answer, and should have been made as a comment to that answer. Your post was flagged by another user (not me; not datageist) as offensive. I took action to keep it on-topic and not denigrating another user.

Computer vision questions was the reason I joined this site. Often they don't seem appropriately places on SO, and yet the Computer Vision proposal has not made it to beta. Indeed, there is a discussion on the proposal site discussing whether to merge CV with DSP. So I'd say, yes - they are on topic, and no - the FAQ already says "for practitioners of ... ...

I'll give you my perspective as a semi-frequent user who isn't part of the community. The site seems kind of dead, which is surprising for a beta with 4,500 visits per day and 260 'avid' users. The two questions I've asked (here and here) both received 1 answer (both fine answers) from users with relatively low reputation. Where are all the 1k+ users? Why ...

I think the comment's author should be encouraged to write a full answer even if they think it's a trivial one. Alternatively, someone else can answer the question giving credit to the comments. I feel that sometimes comments discourage other users from answering a question because they think that the question has already been answered. But comments are ...

I think there should be a separation. The area is close very close, but people are different. The way things now, it makes this forum "Low Quality" for Image Processing to the least and it reflects how things here (Why would you need here simple low quality questions like how to adjust brightness of image in MATLAB here?). In the long run it will make the ...

In light the decision to close the mentioned proposal, I'd like to propose change the name of this Community. Could someone change the community name into Signal & Image Processing? It would bring a lot more people into the forum. Thank You.
