Abstract
A system and method that determine the motion of an absent pixel in a video image. The method may comprise determining the spatial motion and the temporal motion of the absent pixel. The method may also comprise selecting the stronger of the two determined motions. Determining the spatial motion may comprise selecting one of two methods for determining spatial motion. Determining the temporal motion may comprise selecting one of three methods for determining temporal motion. Selection of the methods used may be determined by a user of the system.
Claims24
A method that determines motion information of an absent pixel in a current video image, the method comprising:
- selecting a first method to determine spatial motion of an absent pixel;
- determining the spatial motion of the absent pixel;
- selecting a second method to determine temporal motion of the absent pixel;
- determining the temporal motion of the absent pixel;
- and
- determining the motion of the absent pixel utilizing the determined spatial motion and the determined temporal motion of the absent pixel;
- wherein the first method comprises utilizing a plurality of pixels in a line immediately above and a line immediately below the absent pixel wherein the plurality of pixels comprise:
- a first pixel immediately above the absent pixel;
- a second pixel at the same location as the first pixel in a video image prior to the current video image;
- a third pixel immediately below the absent pixel;
- and
- a fourth pixel at the same location as the third pixel in a video image prior to the current video image.
A system that determines motion information of an absent pixel in a current video image, the system comprising:
- at least one processor capable of selecting a first method to determine spatial motion of an absent pixel;
- the at least one processor capable of determining the spatial motion of the absent pixel;
- the at least one processor capable of selecting a second method to determine temporal motion of the absent pixel;
- the at least one processor capable of determining the temporal motion of the absent pixel;
- and
- the at least one processor capable of determining the motion of the absent pixel utilizing the determined spatial motion and the determined temporal motion of the absent pixel;
- wherein the first method comprises utilizing a plurality of pixels in a line immediately above and a line immediately below the absent pixel, wherein the plurality of pixels comprises:
- a first pixel immediately above the absent pixel;
- a second pixel at the same location as the first pixel in a video image prior to the current video image;
- a third pixel immediately below the absent pixel;
- and
- a fourth pixel at the same location as the third pixel in a video image prior to the current video image.
A machine-readable storage having stored thereon, a computer program having at least one code section that determines motion information of an absent pixel in a current video image, the at least one code section being executable by a machine for causing the machine to perform steps comprising:
- selecting a first method to determine spatial motion of an absent pixel;
- determining the spatial motion of the absent pixel;
- selecting a second method to determine temporal motion of the absent pixel;
- determining the temporal motion of the absent pixel;
- and
- determining the motion of the absent pixel utilizing the determined spatial motion and the determined temporal motion of the absent pixel, wherein the first method comprises code for utilizing a plurality of pixels in a line immediately above and a line immediately below the absent pixel, wherein the plurality of pixels comprise:
- a first pixel immediately above the absent pixel;
- a second pixel at the same location as the first pixel in a video image prior to the current video image;
- a third pixel immediately below the absent pixel;
- and
- a fourth pixel at the same location as the third pixel in a video image prior to the current video image.
