1. A method for region of interest based upscaling for video conferences, the method comprising:
receiving, a video frame of a video conference at a first resolution, and a boundary region for a user-selected object in the video frame, wherein the user-selected object is selected during the video conference;
applying, to a portion of the video frame bound by the boundary region, a machine learning upscaling algorithm to generate an upscaled portion of the video frame corresponding to a second resolution; and
generating an upscaled video frame at the second resolution by combining a first plurality of pixels in the upscaled portion of the video frame corresponding to the user-selected object with a second plurality of pixels.
