视频中的人类对象相互作用(HOI)识别对于分析人类活动很重要。在现实世界中,大多数关注视觉特征的工作通常都会受到阻塞。当HOI中有多个人和物体涉及时,这种问题将更加复杂。考虑到诸如人类姿势和物体位置之类的几何特征提供有意义的信息来了解HOI,我们认为将视觉和几何特征的好处结合在HOI识别中,并提出了一个新颖的两级几何形状特征信息信息图形卷积(2G) -GCN)。几何级图模拟了人类和对象的几何特征之间的相互依赖性,而融合级别的图将它们与人类和对象的视觉特征融合在一起。为了证明我们方法在挑战性场景中的新颖性和有效性,我们提出了一个新的多人HOI数据集(Mphoi-72)。关于Mphoi-72(多人HOI),CAD-1220(单人HOI)和双人动作(双手HOI)数据集的广泛实验证明了我们的表现与最先进的表现相比。

Pixel-aligned Implicit function (PIFu): We present pixel-aligned implicit function (PIFu), which allows recovery of high-resolution 3D textured surfaces of clothed humans from a single input image (top row). Our approach can digitize intricate variations in clothing, such as wrinkled skirts and high-heels, including complex hairstyles. The shape and textures can be fully recovered including largely unseen regions such as the back of the subject. PIFu can also be naturally extended to multi-view input images (bottom row).
