Unsupervised Feature Learning for 3D Scene Labeling• Combining HMP(Hierarchical Matching Pursuit) sliding

window and HMP3D voxel features in an MRF(probabilistic Markov Random Field) framework for labeling objects in 3D scenes reconstructed from RGB-D videos

Object Labeling in 3D Scenes

OASIS (Object-Aware Situated Interactive System)• Recognize and track objects and gestures• Combined with interactive projection• Depth and color information from the RGB-D camera to

recognize different objects• Novel objects can be trained on the fly and recognized in the

future
