EVENT SENSING METHOD AND SYSTEM USING DCT COEFFICIENT IN SURVEILLANCE CAMERA |
| 摘要 |
An event sensing method using a frequency component in a surveillance camera comprises the steps of: obtaining at least one of a plurality of frequency components for a first frame of a digital image and at least one of a plurality of frequency components for a second frame after the first frame of the digital image; and sensing whether an event occurs in a digital image corresponding to the second frame by using the at least one of the plurality of frequency components for the first frame and the at least one of the plurality of frequency components for the second frame. |

1. An event sensing method using a frequency component in a surveillance camera, the method comprising:
obtaining at least one of a plurality of frequency components for a first frame of a digital image and at least one of a plurality of frequency components for a second frame subsequent to the first frame of the digital image; and sensing whether an event occurs in a digital image corresponding to the second frame using the at least one of the plurality of frequency components for the first frame and the at least one of the plurality of frequency components for the second frame. |
