Connected filtering by graylevel classification through morphological histogram processing

Franklin César FloresRoberto de Alencar Lotufo

This paper introduces a new connected filter which provides image simplification in terms of flat zone and graylevel reduction. This filtering consists in application of morphological operators to the histogram. It is done because each object in the image has a significative distribution of graylevels in the histogram. In other words, that is enough to classify the distributions in the histogram for simplification of that objects. It is also shown some experimental results, where the proposed method is compared to other classical ones applied to flat zone and graylevel reduction.
