PDF: Adaptive region of interest processing for panoramic system

Abstract

An adaptive region-of-interest panoramic system is firstly proposed to achieve high-quality and real-time processing for 360-degree panorama. This technique prevents from processing a whole 360-degree image by only focusing on the particular area. Several memory optimizing methods, including cache-miss rate and memory buffer size reduction, are also applied with the purpose of improving the run time performance especially over the mobile devices. Experimental results show that the proposed system can offer 20 frames per second for 4K×2K 360-degree panorama over 2.2GHz Octa-core ARM CPU.
