HON4D: Histogram of Oriented 4D Normals for Activity Recognition from Depth Sequences

We present a new descriptor for activity recognition from videos acquired by a depth sensor. Previous descriptors mostly compute shape and motion features independently, thus, they often fail to capture the complex joint shape-motion cues at pixel-level. In contrast, we describe the depth sequence u...
