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 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.
