Abstract
Methods and apparatus to count people in images are disclosed. An example method includes dividing a frame of image data into a plurality of segments; calculating first fluctuation factors for the respective segments; calculating a second fluctuation factor for the frame; and identifying ones of the segments having a first fluctuation factor greater than the second fluctuation factor as active segments.
Claims20
A method, comprising:
- dividing a frame of image data into a plurality of segments;
- calculating first fluctuation factors for the respective segments;
- calculating a second fluctuation factor for the frame;
- and
- identifying ones of the segments having a first fluctuation factor greater than the second fluctuation factor as active segments.

A tangible machine readable storage medium comprising instructions that, when executed, cause a machine to at least:
- divide a frame of image data into a plurality of segments;
- calculate first fluctuation factors for the respective segments;
- calculate a second fluctuation factor for the frame;
- and
- identify ones of the segments having a first fluctuation factor greater than the second fluctuation factor as active segments.
