Abstract:
1. A method performed by a video coding device, the method comprising: receiving a video frame of a video sequence; applying, in the video coding device, one or more segmentation mode decision factors to the video frame to select a segmentation mode from at least a first segmentation mode and a second segmentation mode, wherein each of the first and second segmentation modes comprise modes of segmenting region of interest (ROI) objects from the video frame and wherein applying the one or more segmentation mode decision factors to select the segmentation mode comprises determining a computational complexity of the video frame by determining a number of ROI features within the video frame and selecting the first segmentation mode when the computation complexity is above a pre-determined level; segmenting, in the video coding device, an ROI object from the video frame without reference to motion information for the video frame when the first segmentation mode is selected; and segmenting, in the video coding device, an ROI object from the video frame based on motion information for the video frame and a different video frame of the video sequence when the second segmentation mode is selected.
