Abstract: 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.

Abstract translation: 一种或多种用于自适应地检测视频中的运动不稳定性的装置和方法。 在实施例中，视频稳定基于运动不稳定性的自适应检测。 自适应运动不稳定性检测可能需要确定与多个视频帧相关联的初始运动不稳定状态。 可以通过将与第一多个帧相关联的不稳定性的第一级别与与第二多个帧相关联的第二级不稳定性进行比较来检测不稳定状态的后续转换。 首先可以基于初始不稳定状态来切换所接收的视频帧的图像稳定性，然后基于检测到的不稳定状态的变化。 然后可以将稳定或不稳定的输出视频帧存储到存储器中。 在某些实施例中，基于视频帧运动抖动值的概率分布对视频运动不稳定性进行评分。

Abstract: Various embodiments are generally directed to techniques for reducing processing and/or storage resource requirements for RDO in compressing motion video. A device to compress motion video includes a first cost calculator to derive a first bitcost value of using a quantized coefficient of a quantized coefficient block of a frame of a video in compressing the video, the first bitcost value based on a context model of a context-adaptive binary arithmetic coder (CABAC); and a second cost calculator to derive a second bitcost value of replacing the quantized coefficient with an alternate value derived from the quantized coefficient in compressing the video, the second bitcost value based on the context model. Other embodiments are described and claimed.
