A method and an apparatus for video frame processing are provided. The method includes: obtaining a convolutional neural network (CNN) feature and a local feature of a target video frame; performing dimension reduction on the CNN feature to obtain a CNN feature with a reduced dimension of the target video frame; obtaining a first video frame from multiple sample video frames, a distance between a CNN feature with a reduced dimension of the first video frame and the CNN feature with the reduced dimension of the target video frame meets a first preset condition; obtaining a local feature of the first video frame; calculating a matching degree between the local feature of the first video frame and the local feature of the target video frame; determining the first video frame as a duplicate video frame of the target video frame if the matching degree meets a second preset condition.

Method and apparatus for video frame processing

Provided is a method for extracting a video segment, including: acquiring a boundary value of content of a video, wherein the boundary value includes an upper boundary, a lower boundary, a left boundary, and a right boundary; acquiring a plurality of first segments by performing key frame segmentation on the video; detecting an upper boundary of subtitles in each of the plurality of first segments; detecting a face position in each of the plurality of first segments; selecting, from the plurality of first segments, a second segment in which the face position satisfies a preset condition; and acquiring a third segment without subtitles by cropping the second segment based on an upper boundary of subtitles in the second segment.

Method and apparatus for extracting video segment, device and storage medium

A method and a device for recommendation of media content are described. The method includes: calculating scores of media content labels in a computer media content library; in descending order of the scores, selecting a first threshold media content label as a candidate media content label; for the candidate media content label, finding out a media content corresponding to the candidate media content label from the media content library; for the media content corresponding to the candidate media content label, in descending order of the amount of page views, selecting a second threshold media content as a media content to be recommended corresponding to the candidate media content label; and recommending the media content to be recommended corresponding to the candidate media content label to a user. The method and device can recommend popular media contents to users, and reduce the style difference between the media contents.

Method and device for recommendation of media content

Embodiments of the present disclosure provide a playlist list determining method and device, an electronic apparatus, and a storage medium. The method comprises: determining feature data of music features comprised in preselected playlists and feature data of music features of preferences of a target user, wherein the music features comprised in the preselected playlists correspond to the music features of the preferences of the target user; calculating correlation coefficients between the feature data of the music features comprised in the preselected playlists and the feature data of the music features corresponding to the preferences of the target user; and determining the preselected playlists to be candidate playlists when the correlation coefficient between the feature data of the music features comprised in the preselected playlists and the feature data of the music features corresponding to the preferences of the target user meets a preset condition.

Playlist list determining method and device, electronic apparatus, and storage medium

Embodiments of the present invention provide a method, an apparatus, and a storage medium for playing control processing of an audio file. The method may include: acquiring an album image corresponding to an audio file to be processed; performing color analysis on the album image, to determine playing colors of the audio file; and performing the playing control processing on the audio file by using the determined playing colors. In the embodiments of the present invention, a personalized playing color can be determined for an audio file, and the playing color of the audio file can effectively represent a style property of the audio file, thereby improving intelligence of playing control processing of the audio file.

Method, apparatus, and storage medium for playing control processing of audio file

The present disclosure provides method and a computer system for tracking audio streaming media. The method includes: after streaming media information matching a currently played audio stream segment is identified, determining whether the streaming media information matches a next audio stream segment, and when the streaming media information matches the next audio stream segment, directly returning a result; or when the streaming media information does not match the next audio stream segment, performing streaming media information matching again for the next audio stream segment, which occupies less memory, improves a calculation speed, and reduces calculation complexity of matching the streaming media information.

Method, system and storage medium for monitoring audio streaming media

A method for calculating a similarity of audio files includes constituting a pitch sequence of a first audio file and a pitch sequence of a second audio file; calculating an eigenvector of the first audio file according to the pitch sequence of the first audio file, and calculating an eigenvector of the second audio file according to the pitch sequence of the second audio file; calculating a similarity between the first audio file and the second audio file according to the eigenvector of the first audio file and the eigenvector of the second audio file.
