Abstract
A method for identifying objects in an electronic image is provided. The method includes the steps of providing an electronic source image and processing the electronic source image to identify edge pixels. The method further includes the steps of providing an electronic representation of the edge pixels and processing the electronic representation of the edge pixels to identify valid edge center pixels. The method still further includes the step of proving an electronic representation of the valid edge center pixels. Each valid edge center pixel represents the approximate center of a horizontal edge segment of a target width. The horizontal edge segment is made up of essentially contiguous edge pixels. The method also includes the steps of determining symmetry values of test regions associated with valid edge center pixels, and classifying the test regions based on factors including symmetry.
