Fast depth estimation on mobile platforms and FPGA devices

Abstract

In this paper, we propose a fast technique for real-time depth estimation that is implementable on mobile devices like smartphones and tablets. Moreover, the FPGA-based implementations of this technique are also reported. The idea of this technique is to use small-block matching and exploit the recently estimated disparity values in order to enhance spatial consistency of the output disparity map. Using the Middlebury stereoscopic test images, the proposed real-time technique is compared to other techniques known from the references. The obtained results demonstrate high efficiency of the proposed technique implemented both on mobile platforms and FPGA devices.Index Terms -depth estimation, mobile application, 3D imaging on mobile, disparity on mobile, FPGA-based disparity estimation

Securing Soft IP Cores in FPGA based Reconfigurable Mobile Heterogeneous Systems

“…Moreover, some FPGA-based systems provide Dynamic Partial Re-configuration (DPR), which allows the run-time update of selected portions of an FPGA without disrupting the rest of the system. DPR allows the creation of new application scenarios [6], [7], [8] and it has already been used in the mobile application market [9], [10], [11]. Hardware vendors are responsible for manufacturing the FPGA devices and sell them to their customers or retailers.…”
