Abstract

The embodiment of the invention discloses a video information processing method, device and system. The method comprises the steps of extracting features of each video frame; judging types of the features, wherein the types reflect time domain correlation degree between the features and reference features; coding the features in preset coding modes matching the types, thereby obtaining coded features; and sending the coded features to a server, thereby enabling the server to decode the coded features, wherein the decoded features are used for visual analysis tasks. Through utilization of the embodiment of the invention, a video does not need to be sent to the cloud server, and the features of the video are coded and then are sent to the cloud server for the visual analysis tasks. Comparedwith the prior art, the method, the device and the system have the advantages that data transmission pressure can be reduced, and storage pressure of the cloud server also can be reduced.

Description

technical field [0001] The present application relates to the field of video technology, and in particular to a video information processing method, device and system. Background technique [0002] In the rapid development of the Internet era, video information, as an accurate, efficient and intuitive multimedia form, is more and more widely used. [0003] The field of visual analysis is one of the important application fields of video information. For example, through visual analysis of surveillance video, functions such as automatic alarm, object detection, and object tracking can be realized; another example, required images can be retrieved from massive videos through visual analysis; and so on. [0004] In the prior art, the visual analysis task is usually performed by a cloud server, and the video to be analyzed is often distributed on multiple terminals (such as monitoring terminals, etc.), and each terminal usually needs to first send the video it collects to the L...
