Sharp constants for weak estimates of the Riesz Potentials
Hanli Tang, Yaojun Wang
In this paper we prove the sharp weak estimates for the Riesz potentials $$\|I_{s}(f)\|_{L^{\frac{n}{n-s},\infty}}\leq γ_{n,s} v_n^{\frac{n-s}{n}}\frac{Γ(s/2)Γ((n+2-s)/2)}{Γ(n/2)}\…

Real-Time Recognition of In-Place Body Actions and Head Gestures using Only a Head-Mounted Display
Jingbo Zhao, Mingjun Shao, Yaojun Wang +1
Body actions and head gestures are natural interfaces for interaction in virtual environments. Existing methods for in-place body action recognition often require hardware more tha…
