    Abstract: Methods, systems and computer program products to increase the efficiency of a trancoding system by providing additional data from a video processor to an encoder, and by providing control signals from the encoder back to the video processor. The video processor may provide variances to the encoder, where these values would not otherwise be available to the encoder or would be computationally intensive for the encoder to generate on its own. The encoder may then use these variances to generate encoded, compressed video data more efficiently. The encoder may also generate control signals for use by the video processor, enabling the video processor to adapt to reconfigurations of the encoder, thereby improving the efficiency of the transcoding operation.

    Abstract: Implementations of a history-based temporal motion noise filtering technique that considers the temporal smooth among multiple pictures as well as the block-based technique to estimate the noise/motion history to better reflect the spatial/temporal smoothness in the local neighborhood are provided. In particular, implementations of the per-pixel blending technique in the block-based noise measurement may be used to better manipulate pixels in both the spatial and temporal domains. A global noise detection technique may be used to estimate the occurrence and/or strength of the noise. A content adaptive spatial filtering content adaptive spatial filter based on a local edge measurement may be used to reduce picture noise as well as preserve edge sharpness. Implementations may be configured for various applications. In particular, programmability options allow users to specify the filter parameters for singularity detection, spatial-only, temporal-only and spatial-temporal filters to achieve user desirable viewing experience.

    Abstract: A video encoder may use an adaptive Wiener filter inside the core video encoding loop to improve coding efficiency. In one embodiment, the Wiener filter may be on the input to a motion estimation unit and, in another embodiment, it may be on the output of a motion compensation unit. The taps for the Wiener filter may be determined based on characteristics of at least a region of pixel intensities within a picture. Thus, the filtering may be adaptive in that it varies based on the type of video being processed.

    Abstract: Systems and methods for video completion. A set of global motion parameters may be determined for a current frame that is to be stabilized. Motion vectors for edge blocks of the current frame may then be calculated. For a prospective new block beyond the current frame, candidate blocks may be generated using a global motion vector and the calculated motion vectors. From the candidate blocks, a candidate block may be selected to be the new block, wherein the selected candidate block may be located at least partially within the outer boundary of the eventual stabilized version of the current frame.
