Embodiment Construction

[0042] 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.

[0043] 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:

[0044] 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;

[0045] Step 202: Identify the foreground area according to the degree of attention of each area in the video frame;

[0046] 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, 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.

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] Insertion of time domain information. 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 informa...
