The question https://dsp.stackexchange.com/questions/24108/what-are-hot-research-topics-in-computer-vision-and-image-processing-for-phd-res doesn't seem appropriate on two accounts:
- It is too vast as well as too vague to define "What is HOT" in DSP.
- .. but more importantly it is also more of a concern to how to choose subject (which could be so for variety of reasons) but doesn't discuss actual DSP issues.
Should this be closed?
or DO we entertain such questions?
