CE13: PERP with horizontal geometry padding of reference pictures (Test 3.3)
Abstract
This contribution reports simulation results of CE13 test 3.3. For inter prediction, horizontal geometry padding of reference pictures is used over conventional repetitive padding at the left and right boundaries for the padded equirectangular projection (PERP). Results based on end-to-end WS-PSNR show that PERP with horizontal geometry padding of reference pictures provides {Y, U, V} BD-rate savings of {-0.22%, -0.29%, -0.38%} over PERP for VTM configuration at a similar complexity as repetitive padding. More importantly, it is reported that horizontal geometry padding significantly reduces the seam artifact issue for the ChairLift sequence.
