Low latency design of Depth-Image-Based Rendering using hybrid warping and hole-filling

A low-latency design of Depth-Image-Based Rendering (DIBR) stereoscopic image generation hardware is presented. We propose a new algorithm that performs the operations of warping and hole-filling in parallel so that the overall computation latency is significantly reduced. Furthermore, two new approaches, “raised disparity around edge” and “horizontal mirroring” are employed to reduce visual artifacts of synthesized virtual images. Experimental results show that the new design can effectively reduce the computation time and improve the synthesized image quality compared to previous DIBR designs.
