摘要:
A method of operating a surveillance system having a display unit configured to display a surveillance image includes acquiring the surveillance image from at least one acquisition device. The method also includes setting surveillance event that includes setting a desired surveillance object indicating an attribute of the surveillance event. Further, the method includes displaying the selected surveillance object with the acquired surveillance image on the display unit to indicate the set surveillance event and analyzing the acquired surveillance image to determine whether the set surveillance event has occurred. In addition, the method includes performing an indicating operation in the surveillance system in response to the occurrence of the set surveillance event.

An object-based bit rate control method and a system therefore provides a user with satisfactory quality of image by using significance of the object. The object is separated from the image, and significance is imposed on each object. A quantization parameter is differently varied according to the significance of the object. Especially, a variable width of the quantization parameter is controlled in a boundary region of the object and the other regions.

A method and apparatus for detecting an object using a perspective plane are disclosed. The method includes determining a perspective plane for a background scene, and determining a moving object within the background scene based upon the determined perspective plane. By using a visual surveillance device and an apparatus for detecting objects, the method and apparatus for detecting an object using a perspective plane is capable of efficiently detecting objects and tracking the movements of the corresponding objects.

The present invention relates to a method for summarizing a news video stream using a synthetic key frame based upon news video text. The method according to the invention generates the synthetic key frame by allocating different importance measures according to an icon text region and a general text region. In the method according to the invention, the highest importance measure is allocated to the icon text region extracted from a news video stream, different importance measures are allocated to general text according to weights, a certain number of general texts are selected, and the synthetic key frame is generated by synthesizing the icon text region and the selected general text regions

The present invention discloses a method for extracting an object region in a motion picture, which can extract the object region of a current frame using different methods based on a degree of motion of the object. Especially, when the object has many motions, an object region of a previous frame is modified by comparing a CDI (Change Detected Image) generated based on a difference between the previous frame and the current frame with the previous frame. As a result, the present invention can be applied to image communication requiring real-time processing, and also applied to techniques requiring precise background change by dividing the object region in pixel units.
