Problems solved by technology

The rapid dissemination of multimedia information has brought great convenience to our life and added a lot of color to our life. At the same time, it is inevitable that some special multimedia information will also be disseminated, such as pornography. , reactionary and other bad information has gradually become a major public nuisance on the Internet; in addition, there are also sounds of babies crying in the surveillance video in the baby room, specific dangerous sounds contained in multimedia information, etc. Due to the particularity of these multimedia information, How to realize its timely and effective detection has become a big problem
[0003] At present, the detection of these special multimedia information is mainly through manual review, but for this detection method, it is extremely subjective, and consumes too much energy and physical strength of the human body, resulting in high labor costs and relatively low processing efficiency.

Embodiment 1

[0112]The mobile terminal receives the instruction information triggered by the user to play a piece of audio information, performs feature extraction on the section of audio information according to the instruction information, and performs frame-by-frame processing on the extracted audio feature information, and obtains 50 frames of audio feature information in total; According to the preset uncivilized audio judgment module, the audio feature information of each frame in the 50 frames is detected respectively, and whether the uncivilized audio feature information is included in the audio feature information of each frame is determined, and the statistics of each frame in the 50 frames are calculated. As a result of the detection, it is determined that the number of frames including uncivilized audio feature information is 15, and in this piece of audio information, if the number of frames including uncivilized audio feature information is greater than 10, it is determined tha...

Embodiment 2

[0115] The mobile terminal receives the trigger indication information that the user is playing a piece of video stream information, performs audio stream conversion on the video stream information according to the trigger indication information, and performs audio feature extraction after conversion into audio stream information, and extracts the extracted audio features The information is divided into frames, and a total of 80 frames of audio feature information are obtained; according to the preset uncivilized audio judgment module, the audio feature information of each frame in the 80 frames is detected separately to determine whether the audio feature information of each frame includes Uncivilized audio feature information, the detection results of each frame in the 80 frames are counted, and the number of frames including uncivilized audio feature information is determined to be 8. In this segment of audio information, if the uncivilized audio feature information is includ...

Embodiment 3

[0118] The mobile terminal collects the trigger indication information that the user is recording a piece of audio information, extracts the features of the audio information according to the trigger indication information, and performs frame processing on the extracted audio feature information, and obtains a total of 40 frames of audio feature information ; The audio feature information of the obtained 40 frames is carried in the uncivilized audio detection request and sent to the server, and the server performs the audio feature information of each frame in the received 40 frames according to the preset uncivilized audio judgment module Detect, determine whether the audio feature information of each frame includes uncivilized audio feature information, count the detection results of each frame in the 40 frames, and determine that the number of frames including uncivilized audio feature information is 20, in this section In the audio information, since the detected number of ...

Abstract

The invention relates to the technical field of computers and discloses a multimedia information detecting method and device. The multimedia information detecting method comprises the steps that framing processing is conducted on multimedia information to obtain multimedia information of each frame; abnormal event detection is conducted on the multimedia information of each frame to obtain a detection result corresponding to each frame; the multimedia information is determined as abnormal event multimedia information according to the detection result of each frame; the multimedia information contains any one of multimedia information which is being played, multimedia information which is being uploaded and multimedia information acquired in real time. In the multimedia information detecting method, the multimedia information of each frame can be specifically processed by conducting framing processing on the multimedia information, the detecting accuracy is improved, then whether the multimedia information is the abnormal event multimedia information or not is determined according to the detection result of each frame, the multimedia information is detected, abnormal event multimedia information detection is achieved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multimedia information detection method and device. Background technique [0002] With the rapid development of the Internet and computer multimedia technology, the way of dissemination of media information has also undergone significant changes. People can easily browse or receive various multimedia information through broadcasting without leaving home. The rapid dissemination of multimedia information has brought great convenience to our life and added a lot of color to our life. At the same time, it is inevitable that some special multimedia information will also be disseminated, such as pornography. , reactionary and other bad information has gradually become a major public nuisance on the Internet; in addition, there are also sounds of babies crying in the surveillance video in the baby room, specific dangerous sounds contained in multimedia information, etc. Due to the...
