Why does not Stack Exchange make one specific page for researchers or anyone with interests in the area of Computer Vision?
Apparently, there was a proposal for a computer vision SE site, but the proposal was deleted because of low activity. In general, if there aren't enough users interested in the topic and enough activity, the site will not be created.
Computer vision is clearly an AI topic, so, in general, any theoretical CV question is on-topic here. See all our CV questions.
Signal Processing SE is also an appropriate site to ask CV questions. In fact, in the past, I've asked some questions there. Stats SE may also be an appropriate site to ask your question.
