Title: (EN) Method and apparatus of determining video image jitter and camera device jitter
(ZH) 一种视频图像抖动和摄像装置抖动判断方法及装置
Abstract: front page image
(EN) The present invention provides a method and an apparatus of determining video image jitter and camera device jitter. The video image jitter determining method comprises the steps of acquiring multiple feature points in a video image at a first moment; tracking the multiple feature points, and determining at a second moment whether content in the image moves drastically according to tracked feature points; if the content in the image does not move drastically, determining a quantity of unmatched feature points in the tracked feature points; and determining, according to the quantity of the unmatched feature points, whether the video image at the second moment jitters compared with the video image at the first moment.
(ZH) 本发明提供一种视频图像抖动和摄像装置抖动判断方法及装置,其中视频图像抖动判断方法包括:在第一时刻获取视频图像中的多个特征点;对所述多个特征点进行跟踪,并在第二时刻根据跟踪到的特征点判断图像中的内容是否发生剧烈运动;当图像中的内容未发生剧烈运动时,确定所述跟踪到的特征点中的不相匹配的特征点的数量;根据所述不相匹配的特征点的数量判断所述第二时刻的视频图像是否相较于所述第一时刻的视频图像发生抖动。
