A Human Activity Recognition System Using Skeleton Data from RGBD Sensors

Figure 2

Subsets of joints considered in the evaluation of the proposed algorithm. The whole skeleton is represented by joints, the selected ones are depicted as green circles, while the discarded joints are represented by red squares. Subsets of (a), (b), and (c) joints, and the whole set of joints (d), are selected.
