Embodiment Construction

[0035] figure 1 A rendering of the method for extracting and associating video interest objects adopted by the embodiment of the present invention is shown. Various aspects of the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0036] Such as figure 2 As shown, a method for extracting and associating a video object of interest provided by an embodiment of the present invention includes:

[0037] Step 201: Generate a degree of attention parameter according to the point information obtained in the rough positioning process, and the degree of attention parameter is used to indicate the degree of attention of each area in the video frame;

[0038] Step 202: Identify the foreground area according to the degree of attention of each area in the video frame;

[0039] Step 203: Perform convex hull processing on the foreground area to obtain candidate objects of interest, and determine the optimal ...

Abstract

The present invention relates to an image and video processing method, especially to a method for extracting and correlating video interested objects based on a two-stage interaction. In the method, a user performs an approximately positioning interaction by using a kind of interaction method which is not limited to a general mode and with a low requirement for priori knowledges, and then performs multiparameter extraction on the interested objects by using a quick and realizable extraction algorithm. Based on the most suitable interested object obtained by the reselection and interaction, the present invention performs searching and weighting by extracting various characteristics to obtain a final result, picks out corresponding images and additional information from a value-added information base, and shows the information at peripheral of the video. The method correlates the value-added information to the interested object of the user without influencing watching of the user by fully mining video information and ensuring preference of the user, thereby satisfying the requirment of the user that the area of interest needs to be looked into and further explored.

Description

technical field [0001] The invention relates to the field of image and video processing, in particular to a video object extraction method and an associated method and system. Background technique [0002] With the development of multimedia technology and network communication technology, more and more videos emerge on the Internet, and the demand for playing videos is also increasing rapidly. When playing a video, many video websites and video software adopt the technology of providing related additional information to the video, so that users can obtain enhanced viewing experience. Currently, common video content enhancement methods focus on providing value-added information predefined by video producers, including: [0003] Time domain information is inserted. Refers to buffering at the beginning, pausing, or playing an additional piece of relevant information at the end of a video. [0004] Peripheral information association. Refers to displaying value-added informat...
