This paper presents a real-time HD1080p view synthesis engine based on the reference algorithm from 3-D video coding team by solving high computational complexity and high memory cost problems. For the computational complexity, we propose the bilinear interpolation to simplify the hole filling process, and the Z scaling method with floating-point format to reduce the cost of homography calculation. For the memory cost, we propose the frame-level pipelining to reduce the requirement of warped depth maps, and the column-order warping method to remove the Z-buffer in occlusion handling. With the 90 nm complementary metal-oxide-semiconductor technology, our view synthesis engine can archive the throughput of 32.4 f/s for HD1080p videos with the gate count of 268.5 K and the internal memory of 69.4 kbytes. The experimental result shows our implementation has the similar synthesis quality as the original reference algorithm. |
