I'm running the "fastcorner" sample on my Galaxy Nexus
The screen shows me that my CamFPS = 16. I was afraid that 16fps is too low for just 'corner detection', so I went to the PreviewCallback, and put a comment on the "update" line, which means that no processing will take place (of course the image is not RGB now so the screen will be black, but that OK for now).
Surprisingly, CamFPS still equals 16!
Which tells me two things (a good one and a not so good one):
1. corner detection is really fast, becuase we gain no more fps if its not done.
2. seems like the starting FPS is very very low (16).
My question is whether I'm doing something wrong or maybe I'm missing something here, but 16FPS with no image processing at all is not a good starting point for a computer vision application.
Are you experiencing the same issue?
