摘要:
A method of extracting a foreground object image from a video sequence includes producing a reference background image by separating a background image from a frame image of the video sequence; producing edge information of the frame image and the reference background image; producing an edge difference image using the edge information; and extracting the foreground object image using the edge difference image based on the edge information.

A system for detecting related topics and competition topics for a target topic includes an information extracting apparatus configured to create topic templates and association words from documents created online to generate topic templates and association words. The system also includes a related topic detecting apparatus configured to detect and trace related topics and competition topics for the target topic based on the topic templates and the association words.
摘要:
A node synchronization apparatus in a wireless network system sets a fast Fourier transform (FFT) start point and requests a one-hop neighbor node to change its transmission time. The synchronization apparatus sets a signal receiving time and requests a one-hop neighbor node to change a receiving time. In this way, a node synchronizes signal transmission and signal reception.
