Magnification enhancement of video for visually impaired viewers

A vision enhancement system for modifying a video stream for display on a display device, comprising:

• a vision analytics system configured to receive a request to display a video stream in a display mode that facilitates viewing by visually impaired viewers, the vision analytics system including:
• a region of interest (ROI) detection system configured to identify an unmodified ROI in a current video frame of the video stream;
• and
• an ROI tracking system configured to track a location of the unmodified ROI in each of the video frames of the video stream subsequent to the current frame;
• a region magnification module configured to magnify the unmodified ROI by a prescribed amount in at least some of the video frames in which the unmodified ROI is being tracked to produce a magnified ROI corresponding to an unmodified ROI;
• and
• an image combining module configured to combine, for each of the video frames in which the unmodified ROI is being tracked and magnified, the magnified ROI with at least a portion of the video frame in which the magnified ROI is located to thereby produce a modified video stream;
• where
• the vision enhancement system includes a trained, automated neural network that automatically identifies the unmodified ROI using an audio component of the video stream.
