android realtime face detection slowing down

[korangko]

first of all, thanks for sharing your code

Im trying to make face detection app in real-time, and when I try this face detection code as thread it slows down after about 7 ~ 8 minutes. IOW first you can get speed approx 54ms to detect face in frame, after 8 min thread gets slowly slow down till 74ms to detect. any suggestion or information? thanks

Do you mean the algorithm will slow down after running several minutes? If so, is it because android reduces the CPU speed to save energy?

I don't think cpu's saving energy sequence is causing slowing down. because other threads which run at the same time, don't have the same issue.
