Abstract
Systems and methods for producing high-quality image segmentation masks by efficiently augmenting low-quality segmentation masks initially obtained by lightly trained neural networks are disclosed. Sequences of low-quality segmentation masks are transformed into high-quality segmentation masks by first identifying groups of pixels that are consistently segmented in at least three successive video frames. The pixels surrounding the consistently segmented pixels are then examined and assigned gradient alpha values, i.e., degrees of transparency. In one embodiment the alpha values are made proportional to the RGB distance of the pixel from the mean RGB value of the consistently segmented group of pixels.
