Abstract
AbstractMulti‐person novel view synthesis aims to generate free‐viewpoint videos for dynamic scenes of multiple persons. However, current methods require numerous views to reconstruct a dynamic person and only achieve good performance when only a single person is present in the video. This paper aims to reconstruct a multi‐person scene with fewer views, especially addressing the occlusion and interaction problems that appear in the multi‐person scene. We propose MP‐NeRF, a practical method for multi‐person novel view synthesis from sparse cameras without the pre‐scanned template human models. We apply a multi‐person SMPL template as the identity and human motion prior. Then we build a global latent code to integrate the relative observations among multiple people, so we could represent multiple dynamic people into multiple neural radiance representations from sparse views. Experiments on multi‐person dataset MVMP show that our method is superior to other state‐of‐the‐art methods.
