A 360-degree 4K×2K pan oramic video processing Over Smart-phones

A 4K×2K video processor supporting 360-degree processing over the smart-phone is first-reported. Two 182° fisheye cameras are exploited to warp and blend the circle video into a 4K panorama one. Fast blending architecture reused the memory buffer and reduce the unused operating area while keep high blending quality, and therefore achieve 4K 360-degree, equivalently 1K 90-degree video processing over 2.5GHz octa-core ARM CPU and Power VR GPU. From the experiment, he proposal achieves 1024×512@15fps which is 3.9 times higher than the state-of-the-art design [6].
