The present invention is applicable to the technical field of panoramic videos. Provided are a panoramic video clip method, apparatus and device, and a storage medium. The method comprises acquiring a panoramic video photographed by means of a panoramic camera, and recording an advancing-direction viewing angle of the panoramic camera during moving photographing; carrying out a frame extraction operation on the acquired panoramic video to obtain a corresponding panoramic video frame, carrying out significant target detection on the panoramic video frame, tracking a detected significant target by using a preset target tracking algorithm, and acquiring a viewing angle at which the tracked significant target is located; and clipping the panoramic video according to the advancing-direction viewing angle and the viewing angle at which the significant target is located, so as to generate a target video corresponding to the panoramic video. A panoramic video is automatically clipped, and the fluency of transitions, and the effectiveness and the degree to which content in a target video is interesting are also ensured.

A watermark detection method includes identifying, among plural stored videos, a second video having a second video feature matching a first video feature of a first video, the second video comprising watermark information. The method further includes comparing the first video and the second video to obtain a video conversion parameter, the video conversion parameter indicating a difference between the first video and the second video. The method also includes converting the first video based on the video conversion parameter to obtain a third video, and performing watermark detection on the third video to obtain watermark information in the third video. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

In a method for selecting of a prerecorded media file for superimposing into a video, a video of a scene is displayed on a display device of a mobile electronic device. A location of the scene is determined. A prerecorded video file is selected based at least in part on the location. The prerecorded video file is superimposed over the video, such that the video is partially obscured by the prerecorded video file. The prerecorded video file is played while displaying the video, such that the prerecorded video file and a non-obscured portion of the video are rendered simultaneously.

Methods, apparatus, systems and articles of manufacture are disclosed to reduce false crediting of exposure to video-on-demand media assets. Example apparatus disclosed herein include a signature matcher to compare a sequence of monitored media signatures to sequences of reference signatures representative of corresponding reference media assets, the sequence of monitored media signatures included in monitoring data reported by a media device meter, the sequences of reference signature stored in a library of reference signatures. Disclosed example apparatus also include a matched assets counter to determine a count of ones of the reference media assets represented by corresponding ones of the sequences of reference signatures determined to match the sequence of monitored media signatures. Disclosed examples further include a credit determiner to determine whether to credit media exposure to a first one of the reference media assets based on the count.

Systems and methods are described to enhance interactive engagement during simultaneous delivery of serial or digital content (e.g., audio, video) to a plurality of users. A machine-based awareness of the context of the content and/or one or more user reactions to the presentation of the content may be used as a basis to interrupt content delivery in order to intersperse a snippet that includes a virtual agent with an awareness of the context(s) of the content and/or the one or more user reactions. This “contextual virtual agent” (CVA) enacts actions and/or dialog based on the one or more machine-classified contexts coupled with identified interests and/or aspirations of individuals within the group of users. The CVA may also base its activities on a machine-based awareness of “future” content that has not yet been delivered to the group, but classified by natural language and/or computer vision processing. Interrupting the delivery of content substantially simultaneously to a group of users and initiating dialog regarding content by a CVA enhances opportunities for users to engage with each other about their shared interactive experience.

The present application discloses techniques of interacting with live videos. The techniques comprise obtaining a streaming video of a live streamer and images of a user captured in real time by a user terminal, and displaying the streaming video and the image of the user in a same video play box; obtaining and recognizing a first gesture of a user in the images of the user, and comparing the first gesture with a second gesture included in a preset table, wherein the preset table comprises information indicating corresponding relationships between gestures and special effects; obtaining a first special effect corresponding to the second gesture by querying the preset table when the first gesture matches with the second gesture; and displaying the first special effect in the video play box.

Methods, apparatus, systems and articles of manufacture to reduce false positive signature matches due to similar media segments in different reference media assets are disclosed. Example apparatus disclosed herein include a signature matcher to compare monitored media signatures with a library of reference media signatures, the monitored media signatures associated with monitored media, the library of reference media signatures including sequences of reference signatures associated with respective reference media assets. Disclosed example apparatus also include a match information identifier to identify a number of different matched reference media assets associated with ones of the sequences of reference media signatures that match a sequence of matched monitored media signatures. Disclosed example apparatus further include a false positive identifier to, in response to the number of different matched reference media assets satisfying a threshold number, eliminate one or more of the matched reference media assets from being credited to the monitored media.

A media source is configured to provide a media stream that includes an audio-video recording. The audio-video recording comprises image frames. A video presentation device receives the media stream provided by the media source and selects a portion of the image frames of the media stream. The device determines, based at least in part on characteristics of the video presentation device and properties of the selected portion of the image frames, a processing resource for executing an algorithm configured to determine a probability that the media stream includes synthetic media. The selected portion of the frames and an indication of the algorithm are provided to the processing resource. The processing resource executes the algorithm to determine the probability that the media stream includes synthetic media. The audio-video recording and a representation of the probability that the media stream includes synthetic media are displayed.

Methods, apparatus, systems and articles of manufacture are disclosed. An example apparatus includes a controller to cause a people meter to emit a prompt for input of audience identification information at a first time and determine a first audience count based on the input, an audio detector to determine a second audience count based on signatures generated from audio data captured in the media environment, and a comparator to cause the people meter to not emit the prompt for at least a first time period after the first time when the first audience count is equal to the second audience count.

A display apparatus, a display management module and a method for ambient light compensation are described. The display management module is configured to receive an input video signal comprising a sequence of video frames and to determine whether a current video frame of the sequence of video frames immediately follows a scene change. The display management module is further configured to adjust ambient light compensation applied to the input signal in dependence on the signal indicative of intensity of ambient light only in response to determining that the current video frame of the sequence of video frames immediately follows a scene change.
