Abstract

The invention belongs to the technical field of computers, and specifically relates to a method of extracting information from multimedia files, and terminal equipment. The method of extracting information from multimedia files includes the steps: acquiring multimedia files to be processed, and separating the video information and the audio information from the multimedia files; extracting the human voice information from the audio information, and converting the human voice information into the text information; extracting the face image from the video information, and acquiring the characteristic vector of the face image; inputting the characteristic vector of the face image into a preset expression classifier so as to determine the expression information corresponding to the characteristic vector of the face image, wherein the expression classifier is obtained by using a machine learning algorithm to train the face expression samples in a specified face expression library; and adding the expression information into the text information, and according to the expression information, determining and identifying the key content of the text information, thus greatly saving the time acquisition time of users.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method for extracting information from multimedia files and terminal equipment. Background technique [0002] When conducting important meetings and training sessions, the audio and video information of the entire process is generally recorded for future study or organization. However, the duration of meetings and training sessions is often tens of minutes or even several hours. If users want to get a complete Content, it takes a lot of time to watch the recorded audio and video content, which is time-consuming and labor-intensive, and it is difficult to extract the key content. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a method and a terminal device for extracting information from multimedia files, so as to solve the problems of time-consuming and labor-consuming and difficult to extract key content whe...
