First Claim
Patent Images
1. A method for identifying a symmetric object in an image represented as an edge map, the method comprising:
- (a) converting the edge map into a binary image map comprising binary pixel values;
(b) dividing the binary image map within a scanning window into a plurality of bins;
(c) summing binary pixel values in each bin; and
(d) identifying the symmetric object based at least in part on the summed binary pixel values in the bins.

Abstract
A symmetric object in an image is identified by (a) converting an edge map of the acquired image into a binary image map including binary pixel values; (b) dividing the binary image map within a scanning window into multiple bins; (c) summing binary pixel values in each bin; and (d) identifying the symmetric object based at least in part on the summed binary pixel values in the bins.
