Patent ID: 7982771

Claim:
A method for emendation of attention trajectory of a viewer visual focus in a video sequence comprising the steps of: extracting attention area image information of a viewer's visual focus for each frame of the video sequence, each attention area image of a frame selectively being a reference for the other frames; projecting the attention image area for each reference to a current frame; and determining an enhanced attention area image of the current frame, wherein the projecting step additionally comprises steps of: imaging the attention areas image from the reference to the current frame; and moving the imaged attention area image to a new position according to an estimated motion vector of the attention area of the reference; the step of determining the enhanced attention area image of the current frame is performed by collecting and merging all the projected attention areas together with the original attention area of the current frame to delete short life attention or noise as to emend the attention trajectory of the video sequence which smoothes the attention trajectory of the video sequence.
