Abstract: A method and a system for adaptively (dynamically) reducing quantization layer reduction for removing quantization artifacts in quantized video signals is provided. Adaptively reducing quantization layer reduction involves detecting if a selected pixel in a quantized image belongs to a ramp area in each of multiple pre-defined directions, dynamically selecting a quantization level for each of the pre-defined directions based on the corresponding detection results, and refining the pixel based on the selected quantization levels.

Abstract: A system and method which determines an adaptive vertical search range used to provide motion estimation in digital video content are disclosed. In some embodiments, a fixed-size vertical search range for the motion estimation is defined and utilized. A reference frame and target frame are stored in memory, and a block in the reference frame is selected for consideration. An offset value is determined which is indicative of a directional shift of the fixed-size vertical search range and the vertical search range is shifted based on the offset value. A motion vector is then estimated using the shifted vertical search range.

Abstract: A system and method for video frame interpolation are disclosed. In one embodiment, the method comprises receiving first motion estimation data representing estimated motion of blocks between a first frame and a second frame, receiving second motion estimation data representing estimated motion of blocks between the second frame and a third frame, determining whether an area in an interpolated frame between the first and second frame is an occlusion area based at least in part on the first and second motion estimation data, and estimating characteristics of pixels of the area based in part on the determination.

Abstract: In certain embodiments, overlap operators are applied during encoding and/or decoding of digital media, where the overlap operators have reduced DC gain mismatch and/or DC leakage between interior overlap operators and overlap operators at the edge and/or corner. In other embodiments, information indicating a selected tile boundary option for overlap processing can be encoded and/or decoded. The selected tile boundary option indicates one of a hard tile boundary option and a soft tile boundary option for processing with overlap operators. Overlap transform processing can then be applied based at least in part on the selected tile boundary option.

Abstract: A system and method for determining a pixel characteristic of pixels in interpolated frames. Preceding and successive frames are evaluated to determine if there is a frame-wide change occurring to the pixels. To the extent there is a frame-wide change, the pixel characteristic in interpolated frames is accommodated by the frame-wide change. In one implementation, frame-wide changes in luminance, such as fade in and fade out, are detected and the pixel characteristic of pixels in the interpolated frame is determined based at least in part on fallback techniques rather than motion compensation interpolation.

Abstract: Three block concepts are introduced in HEVC: coding unit (CU), prediction unit (PU), and transform unit (TU). The overall coding structure is characterized by the various sizes of CU, PU and TU in a recursive fashion. For transform processing in current HEVC, a hierarchy RQT (Residual Quad Tree) is used and the TU size is related to the CU size, but independent of the PU size. This results in high encoding complexity and also causes increased processing time to process the syntax of residual quad tree. Accordingly a modified transform unit partition with reduced complexity is disclosed. According to an embodiment, the TU size may be restricted to the minimum of PU width and height, except for a 2N×2N coding unit with the 2N×2N partition type. In another embodiment, the maximum TU size equals to maximum of PU width and height, and the minimum TU size equals to minimum of the PU width and height, except for a 2N×2N coding unit with the 2N×2N partition type.

Abstract: The present disclosure provides systems and methods for detecting and interpolating still pixels. In certain embodiments, the systems and methods establish a still pixel level for each still pixel, and using that still pixel level, provide an interpolation procedure for determining the pixel value of a selected pixel at a frame a distance ? from frame F(t?1).

Still pixel candidates may be refined in a process where pixels that may be properly handled by standard motion compensation interpolation techniques are eliminated.

Abstract: A one-pass picture-layer rate control (RC) method and system for controlling a video encoder: The bit allocation and determination of quantization parameter (QP) in this rate control method and system are based on a Rate-Quantization (R-Q) scale model. The R-Q model is a linear one, wherein the number of bits per picture is in reverse ratio of quantization scale for that picture. A conversion of exponential-based QP to linear-scaled QP is taken in the calculation of complexity model and determination of QP. The conversion is integer-based and is consistent with the quantization array defined in the H.264 standard.

Abstract: An image processing system implements recursive 3D super precision for processing smoothly changing video image areas by performing temporal noise reduction and then 2D super precision. The temporal noise reduction is applied to two frames, one being the current input low precision frame, and the other being the previous higher precision frame from memory. The 2D super precision is applied to the noise reduced frame to output a high precision frame which is also saved into memory for processing the next incoming frame. The input frame has a limited bit depth while the output image has an increased bit depth.

Abstract: System and methods for the detection of progressive pulldown in a video sequence are provided. The method comprises calculating a difference between temporally adjacent frames in the video sequence, generating a pattern based upon these differences, and comparing the generated pattern against patterns understood for known progressive film modes in order to determine if the video sequence comprises a known progressive film mode. In one embodiment, the pattern may be adjusted to account for uncertainty in assigning values to the pattern, reducing the likelihood of false detections. In another advantage, confidence metrics are built into the method in order to further reduce the incidence of false detections.
