1. A method for selecting a segment boundary comprising:
- determining a segmentation window;
computing a plurality of values associated with candidate boundaries within the segmentation window;
selecting one of the candidate boundaries based at least in part on a comparison between two or more of the computed values; and
determining a boundary within the segmentation window.

Abstract
Selecting a segment boundary comprises determining a segmentation window is determined and computing a plurality of values associated with candidate boundaries within the segmentation window. Selecting a segment boundary further comprises selecting one of the candidate boundaries based at least in part on a comparison between two or more of the computed values and determining a boundary within the segmentation window.

29. A system for selecting a segment boundary comprising:
-
a processor; and a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to; determine a segmentation window; compute a plurality of values associated with candidate boundaries within the segmentation window; select one of the candidate boundaries based at least in part on a comparison between two or more of the computed values; and determine a boundary within the segmentation window.
