slow face detection

[paolobenve]

With high resolution images face detection is - obviously - slow.

Face could be detected after resizing? perhaps detection could be less accurate...

Detecting on resized image only if resized size is bigger than a given value, say, e.g., 1000px?

Face detection is slow when the reduced size images are already on disk, so that face detection happens on original image.

We must resize the image if it's bigger than the thumbnail size
