This also allows the extraction of details about the activity taking place, such as the direction of translational motions, periodicity of motions like boxing, or of more complex periodic motions, containing similarly repeating components (see Section 6.2).
Furthermore, some of the obscene videos may not have periodic motions; therefore, features based on the motion and periodicity characteristics have less impact on the accuracy of the proposed algorithm.
3-D transonic gas flow through the stator and rotor blades in relative motion with periodicity on the whole annulus is described by the unsteady Euler conservation equations, which are integrated using the explicit monotonous finite volume difference scheme of Godunov Kolgan.
Features based on motion and periodicity characteristics.
Features based on motion and periodicity characteristics: 6 elements.
Figure 5 Feature extraction using motion and periodicity characteristics.
(7) Multiple Activity Areas and Activity History Areas originating from the same activity are detected and merged if their motion and periodicity characteristics coincide.
We use three different sets of features for the recognition of obscene videos, namely features based on the information of single frames, features based on 3D STV, and features based on motion and periodicity characteristics.
We present three novel sets of features for the classification of video episodes, including (1) features based on the information of single video frames, (2) features based on 3D spatiotemporal volume (STV), and (3) features based on motion and periodicity characteristics.
Mapping of the control parameters planes in terms of types of motion reveals period-n motion, quasi-periodicity and chaos.
