AHG8: A study on Equi-Angular Cubemap projection (EAC)
Authors: Minhua Zhou Broadcom
Abstract
This contribution studied the compression efficiency of the Equi-Angular Cubemap (EAC) projection, a modified cube map projection format similar to the ACP (Adjusted Cube Map Projection) being studied in the JVET. Experimental results HM16.15 + JVET 360Lib-3.0 library per the 360 video common test conditions revealed that the EAC outperforms the ERP on average by 11.1%, 6.0% and 6.1% (E2E SPSNR-NN, RA-configuration) in Y, U, V, respectively. For E2E WSPSNR measure, the conversion only quality of EAC is about 0.6 dB higher than that of ACP (i.e. 49.12 dB vs. 48.55 dB).
