Stereoview to Multiview Conversion Architecture for Auto-Stereoscopic 3D Displays

摘要

In this paper, a stereoview to multiview conversion system, which includes stereo matching and depth image-based rendering (DIBR) hardware designs, is proposed. To achieve an efficient architecture, the proposed stereo matching algorithm simply generates the raw matching costs and aggregates cost based on 1D iterative aggregation schemes. For the DIBR architecture, an inpainting-based method is used to find the most similar patch from the background, according to depth information. The simulation results show that the designed architecture achieves an averaged peak signal-to-noise ratio of 30.2 dB and structure similarity of 0.94 for the tested images. The hardware design for the proposed 2D to 3D conversion system operates at a maximum clock frequency of 160.2 MHz for outputting 1080p (1920 × 1080) video at 60 frames per second.
