Abstract
In this paper an efficient algorithm for segment digital image has been
developed by measuring the evidence for a boundary between two regions in an image
using (graph-edges). The regions in the image were sorted as components, where each
region in an image represents a component in the graph. The region comparison
predicate evaluates if there is evidence for a boundary between a pair of components
by checking if the difference between the components, is large relative to the internal
difference within at least one of the components. A threshold function is used to
control the degree the difference between components must be larger than minimum
internal difference. An important characteristic of the method is its ability to preserve
detail in important image regions while ignoring detail in unimportant regions. The
classical methods depend just on external difference and ignore the internal
difference, when segment two neighboring regions.
