1. A method for stabilizing camera images captured by a video recording device, the method comprising:

  • identifying candidate regions within a reference frame to use in aligning a frame captured by a video camera, wherein the candidate regions are sorted in descending order by a density of tracked features within each candidate region;

    designating a candidate region having a highest density of tracked features among the candidate regions as an alignment region for each captured frame; and

    upon determining that the stream is unstable based on the tracked features in a current frame being misaligned relative to the corresponding features of the reference frame, aligning the current frame.
