Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] see figure 1 As shown, the live video monitoring method in the embodiment of the present invention comprises the following steps:

[0025] S1: The server obtains the live video address of the live room, obtains the live video stream according to the live video address, analyzes the live video stream to obtain the voice data signal, and transfers to S2.

[0026] S2: The server uses CEEMDAN (CEEmpirical Mode DecompositionAN, a further improved algorithm of the noise-assisted data analysis method. After the signal with poor performance is decomposed by EMD, a series of IMFs arranged from high frequency to low frequency can be obtained, that is, IMFIntrinsic Mode Function, intrinsic Modulus function) performs modal decomposition on the voice data signal to obtain n-order IMF components, n≥3, and then effectively reduces the calculation cos...

Abstract

The invention discloses a live video monitoring method and system, a storage medium and an electronic device, and relates to the field of live video monitoring. The method comprises the following steps: a server analyzes a live video stream to obtain a voice data signal, and the server performs modal decomposition on the voice data through the CEEMDAN to obtain an n-order IMF component; the server separates the n-order IMF component through the FastICA to obtain m reconstructed voice signals, wherein m is not smaller than 1 and is not greater than n-2; the server identifies all reconstructed voice signals, judges whether a reconstructed voice signal containing poor information exists, if so, performs abnormality mark on the current direct broadcasting room; and otherwise, performs normal marking on the current direct broadcasting room. By adoption of the live video monitoring method and system, the noise of the voice data signals can be greatly reduced so as to maximally and perfectly identify the live broadcast voice data, greatly improve the monitoring precision and provide forceful guarantee for the spread of bad information on the Internet.

Description

technical field [0001] The invention relates to the field of live video monitoring, in particular to a live video monitoring method, storage medium, electronic equipment, and system. Background technique [0002] With the rapid development of the live broadcast industry, more and more users like to watch online live broadcasts. In order to avoid the spread of bad information on the network, the live broadcast platform needs to monitor the live video. The existing method for monitoring the live video is generally: artificially monitor the live video of all the live rooms in the live broadcast platform randomly, and when there is a voice with bad information in a certain live room, mark the live room as Focus on monitoring live broadcast rooms; then arrange manual monitoring of key monitoring live broadcast rooms throughout the process, thereby improving monitoring efficiency and purifying live broadcast content. [0003] However, there are following defects in the above-men...
