Abstract
Methods and apparatus for filtering panoramic video signals using visual fixation are disclosed. A panoramic video signal organized into indexed frames is displayed and durations of visual fixations of a viewer of the display are measured by means of detecting the viewer's gaze positions and identifying clusters of adjacent gaze positions. For each visual fixation attaining a prescribed duration threshold, a segment of the panoramic video signal corresponding to a respective view region of prescribed shape and dimensions is extracted to form a filtered video signal. Contents of successive frames of the panoramic signal are cyclically supplied to a bank of content-filtering units operating concurrently to produce individual content-filtered frames which are concatenated for transmission to respective destinations.
