Hi,
These patches(against -next tree) introduce a device driver under drivers/misc for enabling one face detection IP[1] which is integrated inside OMAP4 SoC currently, and have some OMAP4 platform dependent changes to make the module workable on OMAP4 SoC.
For verification purpose, I write one user space utility[2] to test the module and driver, follows its basic functions:
- detect faces in a input grayscal picture(PGM raw, 320 by 240) - plot a rectangle to mark the detected faces, and save it as another same type grayscal picture - set detection parameters
I should have though about implementing a face detection demo on video playback from uvc camera, but OMAP4 DSS on -next tree can't work, so have to quit the idea.
Looks the performance of the module is not bad, see some detection results on the link[3][4].
Face detection can be used to implement some interesting applications (camera, face unlock, baby monitor, ...).
