Embodiment Construction

[0080] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0081] In the related art, in the advertisement processing system, it is necessary to perform advertisement retrieval and prediction. This is actually to perform video repetition detection. However, the workload of manual repetitive detection is very large, the efficiency is low, and the accuracy and precision of repetitive detection are relatively low.

[0082] In order to solve the above technical problems, an embodiment of the present disclosure provides a method for generating a template, which is adapted to be configured in a program, system or device for generating a template, such as figure 1 As shown, in step S101, the first similarity of any two template p...

Abstract

The invention discloses a template generation method, a template generation device, a video updating method and a video updating device. The template generation method comprises steps: statistics on the first similarity between any two template pictures in the template video is carried out; according to the first similarity, multiple template key frame pictures are selected from the template video; each template key frame picture is subjected to DCT transform, and transverse and longitudinal coefficients of pixel point coordinates after transform in each template key frame picture are obtained; according to the transverse and longitudinal coefficients of each template key frame picture, a feature vector for characterizing each template key frame picture is generated; the feature vector is subjected to binary processing, and a template video fingerprint for each template key frame picture is acquired; and a template hash tree is generated according to the acquired template video fingerprint. Through the technical scheme of the invention, video duplication detection can be accurately detected, and the video duplication detection precision and the efficiency are ensured.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a template generating method, a template generating device, a video updating method and a video updating device. Background technique [0002] Currently, in an advertisement processing system, advertisement retrieval and prediction are required. This is actually to perform video repetition detection. However, the workload of manual repetitive detection is very large, the efficiency is low, and the accuracy and precision of repetitive detection are relatively low. Contents of the invention [0003] The present invention provides a method and device for generating a template, and a video updating method and device, which are used to accurately detect video repeatability and ensure the accuracy and efficiency of video repeatability detection. [0004] The present invention provides a method for generating a template, comprising: counting the first similarity of ...
