Abstract: Methods of processing a frame in a video sequence of digital images are described, the methods comprising: determining a global motion vector for the frame relative to a previous frame in the sequence; deriving a jitter function from the global motion vector, the jitter function comprising an estimate of undesired motion of the frame relative to the previous frame; determining whether the frame is blurred above a first predetermined threshold; and if so, stabilising the frame using the jitter function and applying a deblur function to the frame.
Abstract translation: 描述了处理数字图像的视频序列中的帧的方法,所述方法包括:确定所述帧相对于所述序列中的先前帧的全局运动矢量; 从所述全局运动矢量导出抖动函数,所述抖动函数包括所述帧相对于所述先前帧的不期望运动的估计; 确定帧在第一预定阈值之上是否模糊; 如果是,则使用抖动功能稳定框架,并对该帧应用去保护功能。

Abstract: Methods of processing a frame in a video sequence of digital images are provided. The methods include determining a global motion vector for the frame relative to a previous frame in the sequence, deriving a jitter function from the global motion vector, the jitter function including an estimate of undesired motion of the frame relative to the previous frame, and determining whether the frame is blurred above a first predetermined threshold. If the frame is blurred above the first predetermined threshold, stabilizing the frame using the jitter function and applying a deblur function to the frame.
