Embodiment Construction

[0053] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings, but this does not constitute a limitation to the present invention.

[0054] (1) Segment the video and extract key frames;

[0055] (2) Automatically extract the region of interest (ROI) of the key frame, and obtain the ROI image of the key frame;

[0056] (3) Clustering and stratifying the ROIs extracted in step (2);

[0057] (4) The sketch stylizes the keyframes extracted in step (1) to generate a keyframe sketch.

[0058] (5) Using the obtained clustering and hierarchical information, generate an enhanced time axis;

[0059] (6) Receive the sketch annotations input by the user, and combine the hierarchical results obtained in step (3) to generate multi-scale sketch annotations;

[0060] (7) Using the key frame sketch obtained in step (4) and combining the layered resul...

Abstract

The invention relates to a multi-scale video expressing and browsing method. The steps of the method comprise: carrying out preprocessing to videos to be processed at an input end, and users can carry out gesture input and /or noting to the video to be processed. The preprocessed videos load following expressing forms according to orders or breaking timing restriction, and carry out multi-scale expression. An output end chooses the mentioned one or more ways to browse the videos according to the gesture inputting of the users, and outputs browsing results. The multi-scale video expressing and browsing method provides a plurality of different ways to carry out expression and browsing to the users, the limitation of a single expression mode is effectively overcome, the contents from coarse dimensions to finer dimensions can be expressed better according to the requirements of the users, and the users can be helped to understand and locating the contents of the videos. Meanwhile clustering and layering methods relative to the contents are provided, and therefore expressions of the content of different levels are supplied to the users, and different browsing requirements of the users can be met better.

Description

technical field [0001] The invention relates to a multi-scale video processing method, in particular to a multi-scale video representation and browsing method and its realization method, belonging to the technical field of computer applications. Background technique [0002] In today's information society, video, as the most common information carrier, plays a very important role in people's daily life and communication. With the development of software and hardware technologies, the number of videos has also shown explosive growth. Faced with such a large amount of video resources, people have more and more urgent needs for quickly understanding video content, quickly browsing and locating specific plots of videos, etc., and this requires an efficient video representation and interaction method. At present, the presentation, browsing and interaction between people and videos have seriously restricted the further development of video applications. Generally speaking, in the...
