Abstract: A computer adjusts a set of presentation materials, comprising. The computer receives, from a source available to the computer, an initial set of presentation materials. The computer, in response to receiving the initial set of presentation materials, determines a reference presentation duration associated with initial set of presentation materials. The computer receives a target presentation duration from a target duration source available to the computer. The computer determines a presentation conversion value representing, at least in part, a ratio of the target presentation duration to the reference presentation duration. The computer applies a Machine Learning (ML) refactoring routine to revise the initial set of presentation materials in accordance, at least partially, with the presentation conversion value, thereby generating a refactored set of presentation materials having a revised conveyance duration substantially the same as the target duration.

Abstract: Multiple cameras in a conference room, each pointed in a different direction and including a microphone array to perform sound source localization (SSL). The SSL is used in combination with the video image to identify the speaker from among multiple individuals that appear in the video image. Neural network or machine learning processing is performed on the identified speaker to determine the quality of the front or facial view of the speaker. The best view of the speaker's face from the various cameras is selected to be provided to the far end. If no view is satisfactory, a default view is selected and that is provided to the far end. The use of the SSL allows selection of the proper individual from a group of individuals in the conference room, so that only the speaker's head is analyzed for the best facial view and then framed for transmission.

Abstract: The attention level of participants is measured and then the resulting value is provided on a display of the participants. The participants are presented in a gallery view layout. The frame of each participant is colored to indicate the attention level. The entire window is tinted in colors representing the attention level. The blurriness of the participant indicates attention level. The saturation the participant indicates attention level. The window sizes vary based on attention level. Color bars are added to provide indications of percentages of attention level over differing time periods. Neural networks are used to find the faces of the participants and then develop facial keypoint values which are used to determine gaze direction, which in turn is used to develop an attention score. The attention score is then used to determine the settings of the layout.

Abstract: Described are multiple cameras in a conference room, each pointed in a different direction. A primary camera includes a microphone array to perform sound source localization (SSL). The SSL is used in combination with a video image to identify the speaker from among multiple individuals that appear in the video image. Pose information of the speaker is developed. Pose information of each individual identified in each other camera is developed. The speaker pose information is compared to the pose information of the individuals from the other cameras. The best match for each other camera is selected as the speaker in that camera. The speaker views of each camera are compared to determine the speaker view with the most frontal view of the speaker. That camera is selected to provide the video for provision to the far end.

Abstract: Embodiments relate to a system, computer program product, and method for determining missing values in respective data records with an explanatory analysis to provide a context of the determined values. Such method includes receiving a dataset including incomplete data records that are missing predictors and complete data records. A model is trained with the complete data records and candidate predictors for the missing predictors are generated. A predictor importance value is generated for each candidate predictor and the candidate predictors that have a predictor importance value in excess of a first threshold value are promoted. Respective promoted candidate predictors are inserted into the respective incomplete data records, thereby creating tentative data records. The tentative data records are injected into the model, a fit value is determined for each of the tentative data records, and a tentative data record with a fit value exceeding a second threshold value is selected.

Abstract: The development of a region of interest (ROI) video frame that includes only ROIs of interest and not other elements and providing the ROI video frames in a single video stream simplifies the development of gallery view continuous presence displays. ROI position and size information metadata can be provided or subpicture concepts of the particular codec can be used to separate the ROIs in the ROI video frame. Metadata can provide perspective/distortion correction values, speaker status and any other information desired about the participant or other ROI, such as name. Only a single encoder and a single decoder is needed, simplifying both transmitting and receiving endpoints. Only a single video stream is needed, reducing bandwidth requirements. As each participant can be individually isolated, the participants can be provided in similar sizes and laid out as desired in a continuous presence display that is pleasing to view.
