DEBLURRING AND RE-BLURRING IMAGE SEGMENTS |
摘要 |
Using image segmentation in video compression brings about a limitation in video quality when a segment moves in position from frame to frame. The limitation arises because color contributions (bleeding or blurring) naturally occur between neighboring segments. The above-identified problem is overcome by providing solutions to compensate for color contributions between neighboring segments. In accordance with one embodiment, a method and apparatus de-blurs an image segment. De-blurring involves removing from the segment approximate color contributions from neighboring segments. This results in a segment that is approximately independent of color contributions from neighboring segments. In accordance with another embodiment, a method and apparatus re-blurs an image segment. Re-blurring involves adding to the segment approximate color contributions from a new arrangement of neighboring segments. This results in more realistic rendering of the segment, as it is located in the new arrangement. |
