Embodiment 1

[0027] refer to figure 1 , shows a flow chart of the steps of a method for judging a video type in Embodiment 1 of the present invention. The method for judging a video type in the embodiment of the present invention includes the following steps:

[0028] Step 101: Obtain video data.

[0029] Step 102: Extract specific frames from video data.

[0030] Specific frames are multiple frames of multiple characteristic periods in the video data, and the number can be set by those skilled in the art according to actual needs, which is not specifically limited in this embodiment of the present invention.

[0031] Step 103: Identify the text information in the specific frame and the screen ratio occupied by the text information.

[0032] The specific frame is multi-frame, and the text information and the screen ratio of the text information in each frame need to be extracted separately.

[0033] Step 104: Determine video features according to text information and text ratio in a spe...

Embodiment 2

[0040] refer to figure 2 , shows a flow chart of the steps of a method for judging a video type according to Embodiment 2 of the present invention. The method for judging a video type according to the embodiment of the present invention includes the following steps:

[0041] Step 201: Obtain video data.

[0042] Step 202: Extract specific frames from video data.

[0043] The specific frames include: a first set number of frames containing sound at the beginning of the video data; a second set number of frames before the end of the video data; and a third set number of frames in the middle of the video data.

[0044] It should be noted that, in a specific implementation process, the first set number, the second set number, and the third set number can be set by those skilled in the art according to actual needs, which are not specifically limited in this embodiment of the present invention. In addition, the numerical values ​​of the three may be the same or different.

Embodiment 3

[0065] refer to image 3 , shows a schematic structural diagram of a server of the present invention. The servers shown in this embodiment include:

[0066] The video acquisition module 301 is used to obtain video data; the frame extraction module 302 is used to extract a specific frame from the video data; the text information identification module 303 is used to identify the text information and the proportion of the text information in the specific frame;

[0067] The video feature module 304 is used to determine the video feature according to the text information and the ratio in the specific frame; the calculation module 305 is used to calculate the probability that the video data is the first type of data according to the video feature and the stored video data in the video database; A type judging module 306, configured to determine whether the video data is the first type of data according to the probability.

[0068] The server provided by the embodiment of the pres...

Abstract

The invention provides a video type judgment method and a server. The video type judgment method is applied to a system formed by the server and a terminal used by at least one user. The video type judgment method comprises the steps of obtaining video data; extracting a specific frame from the video data; recognizing text information in the specific frame and the image proportion occupied by thetext information; determining video features according to the text information in the specific frame and the proportion; calculating the probability of the video data for being a first type of data byapplying the Bayes' theorem according to the video features and video data stored in a video database; and determining whether the video data is the first type of data or not according to the probability. According to the video type judgment method provided by the invention, the classification and judgment for the video can be realized in an application capable of supporting the uploading of theuser.

Description

technical field [0001] The present invention relates to the technical field of computer video processing, and more specifically, to a video type judging method and server. Background technique [0002] With the rapid development of network multimedia technology, the continuous improvement of network transmission speed and the continuous improvement of compression technology, various multimedia information is emerging, digital library, distance education, video on demand, digital video broadcasting, interactive TV, etc. A large amount of multimedia data is used. Among these multimedia information, video is used by more and more people because of its rich content and strong dynamics. Due to the large amount of data and complex content contained in video information, it is difficult to identify videos belonging to a specific category from a large number of videos, so as to achieve efficient information classification and supervision. [0003] Many video applications that supp...
