Abstract:
1. A visual prosthesis comprising: an image processor to process video data from an imager, including a saliency module for separating the video data into a plurality of video streams, including the saliency module selecting at least one video stream from a group containing luminance, color, texture, differently oriented structure, and motion and producing a selected at least one video stream; a visual stimulator to stimulate visual neurons on a patient; the saliency module further including a saliency-based component to process the selected at least one video stream before the video data are input to the visual stimulator, the saliency-based component being configured to apply a saliency algorithm to the selected at least one video stream and alter the video data according to the saliency algorithm; and means for selectively activating electrodes to provide a cue to a visual prosthesis subject as to which region, including regions outside the field of view of the subject, is most salient.
