Abstract
Systems and methods are disclosed for controlling cropping areas of video images to match the allocated area associated with the image in a video conferencing layout. The disclosed methods can protect regions of interest from being cropped. A region of interest within a video image is identified to adjust the cropping in such a way that the region of interest is preserved within the cropped image. The region of interest may be identified based on motion detection or flesh tone detection, for example.
