The size-intensity diagram: a gray-scale granulometric analysis tool

Eduardo TrettelRoberto de Alencar Lotufo

We present a Size Intensity Diagram, based on a gray-scale granulometry. For this we use a cylindrical structuring element with two varying parameters; the radius r and the height (or intensity) k. The measurement associated with this gray-scale granulometry is based on the volume measurement commonly used in the classical gray-scale granulometry. The proposed diagram is therefore a bidimensional space of variables r and k. The variation of both r and k provides the integration of the size and intensity information into a single graphic. This representation can be seen both as adding size information into the histogram and as adding intensity distribution information to the granulometry curve.
