EXTRACTION AND ASSOCIATION METHOD AND SYSTEM FOR OBJECTS OF INTEREST IN VIDEO

摘要

The present invention relates to an image and video processing method, and in particular, to a two-phase-interaction-based extraction and association method for an object of interest in a video. In the method, a user performs coarse positioning interaction by an interactive method which is not limited to a normal manner and has a low requirement for prior knowledge; based on this, a certain extraction algorithm which is fast and easy to implement is adopted to perform multi-parameter extraction on the object of interest. Base on a most suitable object of interest which is obtained from reselection interaction, the method obtains a final result by extracting various features to perform searching and weighting; corresponding images and supplementary information are extracted from a value-added information base, and finally the information is presented at a periphery of the video. In the method, on the basis of mining video information fully and ensuring user preference, in a manner where the viewing of the user is not affected, associate value-added information with the object which the user is interested in, thereby meeting the user's requirement for deeply knowing and further exploring an attention area.
