How can i change haar feature code from floated to fixed?

asked 2013-08-30 00:27:46 -0500

Actually, I have been making face detection on Raspberry pie (Linux). But, Its processing performance(speed) is not enough for my project so I'd like revise 'face detection' library to increase a processing speed. However, I don't know where i should change and revise for that. Would you please what should i do for that ?

oh, try some other things first, like choosing a lbpcascade instead of a haar one.

also scaling the input by half will give exponential speedup.

Like @berak said, start working with properties to reduce the processing time. There is also the minScale and maxScale parameter which has a huge influence if you can limit it correctly.
