An Effective Object Tracking Method of Apparatus for Interactive Hyperlink Video

摘要

The present invention relates to an apparatus and method for tracking an arbitrarily selected object on a video and outputting the tracking information for use in hypervideo. The present invention provides a method for playing, pausing, stopping, and double-speed playback of general video data. The video input unit with the function, automatically detects the transition frame of the input video to define the start and end point of the object tracking, and select or automatically detect the object to be tracked between the scene transition frame to track the object Object tracking unit that stores the tracking information, how to display the tracking object that can be used in hypervideo when storing the object tracking information in the object tracking unit, the type of the shape to display the tracking object, etc. Input the corresponding hyperlink information and save it together with the video. It is made to the output.;The present invention having the configuration described above can be used to combine the well-known similarity comparison method and the bit operation block matching method using the census transformation, and stably track the background and lighting changes or the rotation or size change of the object. It is also suitable for systems such as hypervideo authoring tools that can maximize tracking performance and do not know the information of the object to be tracked in advance.
