Nowadays, 3D-image processing of stereovision that uses two camera lenses has been a vibrant research filed. This paper proposes an efficient hardware architecture for high performance and real-time smoothing filter that is applicable to enhance the disparity map image from 3D stereovision system. First, we maximally utilized the parallel and pipeline operations. Second, we adopted 11 by 11 sparse...
In this paper, we propose a software-level power simulator that measures power consumption for each instruction of RTL processor and builds on a LUT so as to attain low power code generation. Recently, as demands for mobile device with new concept, such as smart phone and tablet PC, have been increasing rapidly, development of low power embedded processor is mandatory. Since these devices usually...
In our related work, we proposed Cognitive Stereo Auto Focus for stereo camera. Instead of moving optical axis, Cognitive Stereo Auto Focus shifts one side image to the opposite side for setting focus. In the shifting process, focus point should be set on the proper place not to cause any side effect produced by visual fatigue to user. To perform low visual fatigue focusing, Cognitive Stereo Auto...
In this paper, a new hardware implementation for the real time disparity map is presented. The real time disparity map includes the Dynamic Search Range Estimation, Disparity estimation, and Error Correction. Our demonstrated design flow shows an approach to implementation and hardware architecture of real-time disparity map estimation. This design is efficiently synthesized on Xilinx vertex 5 VLX...
As requirements of 3D contents have been increased, a matching algorithm to obtain a disparity-map becomes vibrant research field. This processing includes a multi-sliding-window-operation (MSWO) which requires high memory and processing-time consumption. In this paper, we propose an effective hardware architecture with convergence of on-chip memory and shift registers, and parallelized cores. We...
