AssemblyHands-X: Modeling 3D Hand-Body Coordination for Understanding Bimanual Human Activities

Tatsuro Banno, Takehiko Ohkawa, Ruicong Liu +2

Bimanual human activities inherently involve coordinated movements of both hands and body. However, the impact of this coordination in activity understanding has not been systemati…

Generative Modeling of Shape-Dependent Self-Contact Human Poses

Takehiko Ohkawa, Jihyun Lee, Shunsuke Saito +7

One can hardly model self-contact of human poses without considering underlying body shapes. For example, the pose of rubbing a belly for a person with a low BMI leads to penetrati…
