tldr: At present, such questions are probably less likely to get answered here than where they are.
I would have thought you'd have more cog. neuro. folks on CogSci than we would here (I'm one of the few neuroscientists here). While I think one could argue that biological image and signal processing questions fall under the purview of bioinformatics, in practice I don't foresee anyone on the site currently being familiar enough with the topics to offer any real help. Most of the time bioinfo is an umbrella term for NGS, microarray, proteomics and (sometimes) structure. So while I don't personally think such posts are strictly off-topic, I also don't think it's worth migrating them. I hope for this to change in the future as the site's user-base increases.
Update: See also this meta question from earlier. Maybe if we make this site a hub for such questions we can encourage those communities to join. I would certainly welcome that.
