1. A system, comprising:

  • a text recognition component configured for recognition of text on a sequence of video frames, the text recognition component configured to receive a selected frame of the sequence of video frames and perform text recognition processing of the selected frame to output a selected frame result;

    a tracker component configured to select a keyframe from the sequence of video frames based on stability criteria applied to incoming frames and to establish a reference coordinate system relative to the selected keyframe, the selected frame result mapped back to the reference coordinate system of the keyframe, the tracker component configured to apply keyframe coordinates to subsequent video frames to enable accumulation of best results for text recognition rendering and viewing; and

    a microprocessor configured to execute computer-executable instructions associated with at least one of the text recognition component or the tracker component.
