Problems solved by technology

[0007] These two methods can achieve good image labeling effects when the amount of data is small and the real-time requirements are not high. However, for massive video resources, the computing resources of a single machine obviously cannot support large-scale calculations, so the algorithm cannot be applied to Massive video annotations

Embodiment Construction

[0035] The present invention is based on the massive video semantic labeling method of Spark, and the steps are as follows:

[0036] The first step is to establish a Hadoop / Spark massive video big data platform. The platform is composed of three parts: management module, structure module and data module, which are independent of each other to realize flexible storage of massive data. Independent maintenance and upgrade, flexible handling of system redundancy and backup. Such as figure 2 As shown, the management module provides a set of access interfaces to the operating system (client), mainly including: creating, opening, closing, revoking, reading, writing, rights management, etc. for files and directories. The operating system (client) obtains various services of the data storage system through these access interfaces. The structure module creates corresponding data tables in the database for data files of different structures, and the table describes file attribute info...

Abstract

The present invention proposes a Spark-based massive video semantic tagging method, which is mainly based on elastic distributed storage of massive videos in a Hadoop big data cluster environment, and uses Spark computing mode for video tagging. The method mainly includes the following contents: video segmentation method based on fractal theory and its implementation on Spark; video feature extraction method based on Spark and visual word formation method based on meta-learning strategy; generation method of video annotation based on Spark. Compared with traditional stand-alone computing, parallel computing or distributed computing, the present invention improves the computing speed by more than a hundred times, and has the advantages of complete labeling content information, low error rate, and the like.

Description

technical field [0001] The invention relates to a video processing method, in particular to a Spark-based massive video semantic tagging method. Background technique [0002] In recent years, with the popularity of multimedia applications and social networks, various multimedia data (text, images, and videos, etc.) have shown exponential growth; these large-scale data give traditional multimedia research, especially based on video applications and Research has brought new challenges and opportunities. How to effectively organize and use video data to drive and satisfy users' various personalized needs for video is becoming a research hotspot in the field of computer vision and multimedia. [0003] There is a big gap between the video understood by humans and the video expressed by the underlying visual features, that is, there is a "semantic gap" between video semantics and visual features. In order to achieve a query method described in natural language that is closer to t...
