  • Abstract Standared 3D stereo showing images at different view positions requires images captured from various view angles and thus needs large transmission bandwidth. In this thesis, the vitual images at different viewing locations are generated from an image and a depth map using depth-image-based rendering (DIBR) where the depth map is obtained using stereo matching based on dynamic-programming (DP). To reduce the geometry distortion in DIBR due to the mismatch of source images and depth information, we propose a depth-map preprocessing method by modifying the depth information near the image edges. Regarding disocclusion, horizontal extrapolation and background mirroring are adopted for hole filling in order to improve the quality of synthesized virtual images. Depth-map preprocessing, image warping and hole filling are executed in pipelining in the proposed DIBR hardware. Furthermore, we combine the hardware of DP-based stereo matching for depth map geneneration and the subsequent DIBR for virtual image synthesis by processing the image sequences scanline by scanline so that the area cost of the overall system is reduced with satisfactory performance.
