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, ...). arch/arm/mach-omap2/devices.c | 33 + arch/arm/mach-omap2/omap_hwmod_44xx_data.c | 81 +++ drivers/misc/Kconfig | 7 + drivers/misc/Makefile | 1 + drivers/misc/fdif.c | 874 ++++++++++++++++++++++++++++ include/linux/fdif.h | 67 +++ include/linux/major.h | 1 + 7 files changed, 1064 insertions(+), 0 deletions(-) thanks, -- Ming Lei [1], Ch9 of OMAP4 Technical Reference Manual [2], http://kernel.ubuntu.com/git?p=ming/fdif.git;a=summary [3], http://kernel.ubuntu.com/~ming/dev/fdif/output [4], All pictures are taken from http://www.google.com/imghp and converted to pnm from jpeg format, only for test purpose. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
