Abstract: Methods and systems for video coding are provided. A method includes receiving a digital video stream. The digital video stream includes multiple sequential independent frames. The method further includes storing a first frame of the digital video stream. The method also includes encoding a second frame of the digital video stream using motion compensation with the stored first frame as a reference.

Abstract: Methods, systems and computer program products for providing a deblocking algorithm to one or more blocks in a picture are described. A filtered block may result for each deblocked block. Each filtered block may then be combined to generate a decoded deblocked picture. This process may subsequently be applied to a next picture in a group of pictures resulting in a deblocking of a coded video sequence.

Abstract: An apparatus, method, and computer program product for processing a video bitstream includes determining a variance of the variance values for a selected pixel based on a group of pixels in the video bitstream to produce a variance of the variance value for the selected pixel; selecting one of a plurality of filters based on the variance of the variance value for the selected pixel; and applying the selected filter to the selected pixel.

Abstract: An apparatus and method for removing undesired material from the surface of a substrate provides a flow of inert gas over the undesired material substrate surface while irradiating the undesired material with energetic photons directed at an angle that is oblique to the substrate. The invention enables removal of undesired material without altering the physical properties of the material underlying or adjacent the removed, undesired material. In certain circumstances, the non-perpendicular incidence permits effective removal where normal incidence caused damage to the substrate or poor removal or both.
