Method of emendation for attention trajectory in video content analysis

视频序列中感兴趣区域的校正方法

Abstract

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 attentiontrajectory 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.
本发明揭示一种视频内容分析中感兴趣区域轨迹的校正方法。该方法包括:提取视频序列中每一帧的感兴趣区域的步骤,一帧中的每个感兴趣区域可选择性地作为其它帧的参考;将参考感兴趣区域投影到当前帧的步骤;以及通过集中和合并所有投影感兴趣区域以及当前帧的原始感兴趣区域,确定当前帧的一个增强的感兴趣区域,来校正视频序列的感兴趣区域轨迹,使感兴趣区域轨迹平滑的步骤。有利的是,忽略了短期感兴趣区域或噪声,同时还丰富了感兴趣区域,因而,感兴趣区域轨迹的平滑可以改善人们的主观观看感受。
