    • A method for emendation of attention trajectory in video content analysis is disclosed. The method includes steps of extracting attention area for each frame in a video sequence, each attention area of a frame selectively being a reference for the other frames, projecting the attention area of the reference to a current frame, and determining an enhanced attention area of the current frame by collecting and merging all the projected attention areas together with the original attention area of the current frame to emend the attention trajectory of the video sequence so as to make the attention trajectory smooth. Advantageously, short-life attention or noise is omitted, and the attention area is also enriched, therefore, the smooth of the attention trajectory improves subjective viewing experience of human being.
    • 公开了一种视频内容分析中注意轨迹的修复方法。 该方法包括以下步骤:提取视频序列中的每个帧的注意区域,帧的每个注意区域选择性地作为其他帧的参考,将参考的注意区域投射到当前帧,并且确定增强的注意区域 通过收集和合并所有投影的关注区域以及当前帧的原始注意区域来发布视频序列的注意轨迹,以使注意轨迹平滑,从而当前的帧。 有利地,省略了短时间的注意力或噪音,并且还增加了注意力区域,因此,注意力轨迹的平滑性改善了人的主观观看体验。
