Implementation and optimization of software depth estimation for arm

3D imaging capable devices have been available on the market for a few years now and the availability of 3D contents is also picking up. However, 3D contents available for viewing is not growing fast enough to meet the demand. To compensate for such a problem, most 3D imaging devices are equipped with 2D to 3D conversion function. Also, common 3D contents available are mostly produced with 2 view points which poses a problem for autostereoscopic devices that is capable of displaying multiple view points. In the absence of multiview 3D contents, to produce natural viewing experience on such device, depth estimation is an essential technology in order to create more parallax images from source images. In this paper, we present the implementation of Toshiba´s software depth estimation process on ARM processor which allows realtime processing on embedded devices such as TVs, mobile phones and tablet computers adopting stereoscopic or autostereoscopic 3D technology.
