ReMagicMirror: Action Learning Using Human Reenactment with the Mirror Metaphor
We propose ReMagicMirror, a system to help people learn actions (e.g., martial arts, dances). We first capture the motions of a teacher performing the action to learn, using two RGB-D cameras. Next, we fit a p...

Ultra-Shallow DoF Imaging Using Faced Paraboloidal Mirrors
We propose a new imaging method that achieves an ultra-shallow depth of field (DoF) to clearly visualize a particular depth in a 3-D scene. The key optical device consists of a pair of faced paraboloidal mirro...
