Embodiment

[0067] In order to make the purpose, technical solution and advantages of the present invention clearer, the following briefly introduces the application of the time-axis video compression technology in China Telecom's Global Eye service.

[0068] China Telecom's global eye network video monitoring platform is based on a high-performance, highly integrated large-scale remote monitoring system. business. It is a network video surveillance system composed of front-end, middle-end and back-end. The front end is composed of lens, camera, pan / tilt, alarm switch, video codec equipment, host control equipment and monitoring software; the middle end is the central service platform provided by the telecommunications company. The central service platform has the management function of the business platform and provides The incoming images are forwarded, distributed or stored, and the alarm is processed in linkage; at the back end, the user can watch the video arbitrarily after passing ...

Abstract

The invention discloses a method and a device for generating video abstraction. The method includes: acquiring key frames according to intelligent video stream frame-grabbing algorithm; extracting and classifying backgrounds and objects in the key frames using background compensation algorithm; dividing into a plurality of video data having similar time duration on the basis of a time shaft according to motion track of the objects, and overlapping with the backgrounds having the same time duration to generate the video abstraction. By the method, more historical video data can be saved with less storage space.

Description

technical field [0001] The invention relates to the fields of image communication, image analysis and the like, and in particular to a method and device for generating video summaries. Background technique [0002] With the vigorous rise of multimedia technology, video capture technology, and Internet applications, the gradual evolution of video surveillance, image compression coding, and streaming media technology has made video surveillance technology more and more widely used in daily life. [0003] The expansion of image business applications has made video surveillance not only limited to security protection, but has become an effective means of supervision for all walks of life. The flexibility of its application field has far exceeded the traditional security protection Monitor the defined categories. In the past two years, a brand-new concept of Telecom Global Eye full-digital network video surveillance system is being widely used. In fact, video surveillance has a...
