摘要： An apparatus and method for facilitating a subsequent choice of a motion vector from a plurality of candidate motion vectors in a motion estimation method, include receiving video image data from first, second and third consecutive groups (10, 20, 30) of image data. A first image part (12) of the first group of image data (10), a second image part (22) of the second group of image data (20), and a third image part (32) of the third group of image data (30) are identified, wherein the positions of the three image parts (12, 22, 32) correspond to a motion trajectory that is indicated by a candidate motion vector. A first error measure is then calculated by testing for differences between the first image part (12) and the third image part (32) and quantified as a first error measure. A second error measure is calculated by testing for differences between either the first image part (12) and the second image part (22) or the second image part and the third image part and quantified as a second error measure. An output error measure is then quantified, wherein the output error measure is derived from either the first or the second or a combination of both error measures.

摘要： A control signal (k_lum) derived from the luminance component (Y) of a video signal is used to adaptively control a temporal noise reduction filter (10) according to the level of motion in a video image. To compress the control signal for storage in a memory (30), the control signal is averaged over each 2×2 pixel area, and then a non-linear compression function is applied. The non-linear compression function preferably selects quantization values of the control signal which correspond to a perceptually substantially linear response in the noise reduction factor (NRF) of the noise filter (10).

摘要： One embodiment of the present invention discloses a method for processing video data within a video data processing path of a processing unit. The video data processing path includes three stages. In the first stage, source operands are extracted from a local register file and are ordered to map efficiently onto the downstream data path. In the second stage, arithmetic operations are performed on the source operands based on video processing instructions to generate intermediate results. In the third stage, additional operations are performed on the intermediate results based on the video processing instructions. In some embodiment, the intermediate results are combined with additional operands retrieved from the local register file.

摘要： A method includes projecting motion vectors describing a transformation from a previous video frame to a future video frame onto a plane between the previous video frame and the future video frame, detecting potential artifacts at the plane based on an intersection of a cover region and an uncover region on the plane, and analyzing a dissimilarity between a trial video frame and both the previous video frame and the future video frame. The trial video frame is generated between the previous video frame and the future video frame based on a frame rate conversion ratio derived from a source frame rate and a desired frame rate. The method also includes estimating reliability of the projected motion vectors based on the potential artifact detection and the dissimilarity analysis.

摘要： Sub-pixel accurate motion estimation from digital video requires interpolation of data. In a symmetrical motion estimator that shifts the neighboring images over complementary fractions (−D/2, D/2) of the vector (D), two such interpolating filters are required. In case of block-matching motion estimation algorithms, the match error of various candidate vectors depends on the quality of the sub-pixel interpolation filter(s). As these filters differ per fractional value of the vector, unintentional preferences for some fractional vector values over other may result. The candidate vectors (D) are split into an integer part (Rnd(D/2)) and a generally non-integer part (D-Rnd(D/2)), as this gives a better accuracy and a lower cost than splitting the candidate vectors (D) exactly conform the temporal position at which the vectors need to be valid.
摘要翻译： 数字视频的子像素精确运动估计需要插值数据。 在对称运动估计器中，相对于矢量（D）的互补分数（-D / 2，D / 2）偏移相邻图像，需要两个这样的内插滤波器。 在块匹配运动估计算法的情况下，各种候选矢量的匹配误差取决于子像素内插滤波器的质量。 由于这些滤波器对于矢量的每个分数值而不同，因此可能导致某些分数向量值超过其他矢量值的无意偏好。 候选向量（D）被分割成整数部分（Rnd（D / 2））和大致非整数部分（D-Rnd（D / 2）），因为这样得到比分割更好的精度和更低的成本 候选向量（D）完全符合向量需要有效的时间位置。
