Abstract
Many image processing problems are concerned with determining measurements of an anomalous area in an image. Most automated systems suffer from low specificity, which may reduce their acceptance. An example embodiment of the present invention relates to a method and corresponding apparatus for providing measurement data of a region of interest in an image in a graphical user interface environment. The example embodiment locates a pair of edges in multiple dimensions of a region of interest selected by a user, calculates a center position between respective edges, and iterates until a convergence or divergence is determined. Linear calculation may be employed for rapid results, allowing an advance in speed of image processing over current techniques. In a case of convergence, the measurement data is reported. In a case of divergence, a failure state is reported. By reporting divergence, the example embodiment achieves high specificity, thereby reducing the number of false positive reports.
