Hi, These v1 patches(against -next tree) introduce v4l2 based face detection(FD) device driver, and enable FD hardware[1] on omap4 SoC.. The idea of implementing it on v4l2 is from from Alan Cox, Sylwester and Greg-Kh. For verification purpose, I write one user space utility[2] to test the module and driver, follows its basic functions: - detect faces in input grayscal picture(PGM raw, 320 by 240) - detect faces in input y8 format video stream - plot a rectangle to mark the detected faces, and save it as another same type grayscal picture 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, ...). TODO: - implement FD setting interfaces with v4l2 controls or ext controls thanks, -- Ming Lei [1], Ch9 of OMAP4 Technical Reference Manual [2], http://kernel.ubuntu.com/git?p=ming/fdif.git;a=shortlog;h=refs/heads/v4l2-fdif [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
