摘要： One or more apparatus and method for adaptively detecting motion instability in video. In embodiments, video stabilization is predicated on adaptive detection of motion instability. Adaptive motion instability detection may entail determining an initial motion instability state associated with a plurality of video frames. Subsequent transitions of the instability state may be detected by comparing a first level of instability associated with a first plurality of the frames to a second level of instability associated with a second plurality of the frames. Image stabilization of received video frames may be toggled first based on the initial instability state, and thereafter based on detected changes in the instability state.Output video frames, which may be stabilized or non-stabilized, may then be stored to a memory. In certain embodiments, video motion instability is scored based on a probability distribution of video frame motion jitter values.

摘要： Systems and methods for choosing whether to select either a spatial interpolation value or a motion compensation interpolation value for deinterlacing an interlaced frame. A minimal sum of absolute differences (SAD) may be determined for a current pixel. Depending on the magnitude of the minimal SAD relative to two threshold values, different checks may be applied. The outcome of the checks may determine whether the spatial interpolation value or the motion compensation interpolation value may be used in deinterlacing. Generally, the magnitude of the minimal SAD may determine the reliability of the SAD and the consequent trustworthiness of the associated motion vector (MV). Greater reliability of the minimal SAD may suggest that the motion compensation interpolation value may be used for purposes of deinterlacing. Less reliability in the minimal SAD may motivate additional checks to further evaluate whether the motion compensation interpolation value should be used. A less reliable minimal SAD and/or failure of some of the checks may suggest that the motion compensation interpolation value should not be used.
摘要翻译：用于选择是否选择空间插值或用于去隔行隔行帧的运动补偿内插值的系统和方法。可以为当前像素确定绝对差的最小和（SAD）。根据相对于两个阈值的最小SAD的大小，可以应用不同的检查。检查的结果可以确定空间内插值还是运动补偿内插值可以用于去隔行扫描。通常，最小SAD的幅度可以确定SAD的可靠性和相关联的运动矢量（MV）的随后的可信度。最小SAD的更高的可靠性可能表明运动补偿内插值可以用于去隔行扫描。最小SAD中的较低的可靠性可能会激发额外的检查，以进一步评估是否应使用运动补偿内插值。不太可靠的最小SAD和/或某些检查失败可能表明不应该使用运动补偿内插值。

摘要： The format of telecined video may be determined including a bottom field first cadence. In addition, video using 2:3:3:2 top field first can be identified. Moreover, mixed cadence videos can also be detected. In some embodiments, mixed cadence videos may be detected by calculating variances of different areas within a frame.

摘要： A method processes a multiview videos of a scene, in which each video is acquired by a corresponding camera arranged at a particular pose, and in which a view of each camera overlaps with the view of at least one other camera. Side information for synthesizing a particular view of the multiview video is obtained in either an encoder or decoder. A synthesized multiview video is synthesized from the of multiview videos and the side information. A reference picture list is maintained for each current frame of each of the multiview videos, the reference picture indexes temporal reference pictures and spatial reference pictures of the acquired multiview videos and the synthesized reference pictures of the synthesized multiview video. Each current frame of the multiview videos is predicted according to reference pictures indexed by the associated reference picture list.
