Abstract: Embodiments of the present disclosure generally relate to livestreaming methods and systems, and more particularly to whiteboard presentation systems that can be used in a livestreaming or video conferencing environment. In some embodiments, the whiteboard presentation system is configured to perform one or more processing operations, such as capture images on a whiteboard, perform image processing routines on the captured images, and transmit processed images as a video feed to one or more remote users, such as people or locations attending a video conference. The image processing routines can include one or more operations such as image denoising, contrast enhancement, color reconstruction, segmentation of a presenter, and image reconstruction.

Abstract: Embodiments herein generally relate to video-conferencing systems, and more particularly a method and system for optimally grouping and auto-cropping a field of view (FOV) of the video-conferencing system based on predefined preferences, such as preferences determined by a user. Generally, embodiments of the disclosure provided herein include a video-conferencing system that is configured to update the presentation of participants within a video conference to regularly determine the optimal presentation of the participants at any given moment in time based on predetermined preferences, while mitigating defects and related unwanted distractions typically generated in the video conference presentation due to the changes provided in the updates. Embodiments of the disclosure allow the predetermined preferences to each be given an importance level rating so as to allow the presentation of the participants to be optimally provided without making unnecessary and/or distracting updates to the video conference presentation, and also help resolve conflicting or competing attributes of related preferences.
