I am currently working on a facetracking/eyetracking system to measure som parameters from the eyes of that person that is in front of the camera. It uses both detecting and tracking so that I am able to increase the number of fps. I am now up to 21fps while measuring some parameters of the eye. (1.3 ghz processor,so i think that it is quite good, processor=~40-60%) But the resolution of my camera is to low (the camera needs to be to close to the person), but before I buy a new cam with much higher resolution (>=1280x...) i want to ask here if there is someone who have done this before?
Do you think that my system will suffer, with a decreased fps, when increasing the resolution of the camera? While tracking the person/eyes i am only analysing a box of 100x50px, so not the whole cam frame.
I know that this is a very blurry question, but I still want to ask it, and hopefully someone can giver their opinion and thoughts. The cam is excpensive (>500$)
Thanks!
