Embodiment 1

[0068] figure 1 A flowchart showing a method for building a video library according to an embodiment of the present disclosure. This method can be applied to a server, and is not limited here. Such as figure 1 As shown, the method includes step S11 to step S15.

[0069] In step S11, related video sequences are obtained according to the same and / or similar videos in each video.

[0070] In a possible implementation manner, the method may further include: determining videos with the same MD5 (Message Digest Algorithm 5, information-digest algorithm 5) information as the same video.

[0071] In a possible implementation manner, the method may further include: determining a video whose matching degree of the global feature is greater than a first threshold and whose matching degree of the local feature is greater than a second threshold as similar videos. Wherein, the global feature can be the histogram and variance of each video frame of the video, which can reflect the overa...

[0192] Figure 9 It is a block diagram of an apparatus 1900 for creating a video library according to an exemplary embodiment. For example, apparatus 1900 may be provided as a server. refer to Figure 9 , apparatus 1900 includes processing component 1922 , which further includes one or more processors, and a memory resource, represented by memory 1932 , for storing instructions executable by processing component 1922 , such as application programs. The application programs stored in memory 1932 may include one or more modules each corresponding to a set of instructions. In addition, the processing component 1922 is configured to execute instructions to perform the above method.

[0193] Device 1900 may also include a power component 1926 configured to perform power management of device 1900 , a wired or wireless network interface 1950 configured to connect device 1900 to a network, and an input-output (I / O) interface 1958 . The apparatus 1900 can operate based on an operat...

Abstract

The invention relates to a building method and a building device for a video database. The method comprises the steps of acquiring a related video sequence according to the same and / or similar videosin each video; selecting the videos to be selected from each related video sequence; separately using the videos not belonging to the related video sequence as the videos to be selected; sorting eachvideos to be selected; determining recommendation videos from each video to be selected according to a sorting result; and building the video database according to the recommendation videos. Accordingto the method and device provided by the invention, the video quality in the built video database can be improved under the premise of ensuring the database building efficiency, and thus the search efficiency of the user can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of video analysis, in particular to a method and device for establishing a video library. Background technique [0002] How to select high-quality videos from massive videos for users to search is one of the concerns of video website operators. In related technologies, the following two methods are mainly used to establish a video library for users to search. The first way is to manually screen a large number of videos, and build a video library based on the manually screened videos. This method consumes manpower and material resources and is less efficient. The second way is to classify and filter videos according to their titles and keywords through a pre-trained classifier, and build a video library based on the screened videos. Since the title and keywords of the video may not be related to the content of the video, the effect of the video library built in this way is relatively poor. Conte...
