Connected filtering by graylevel classification through morphological histogram processing

The paper introduces a new connected filter which provides image simplification in terms of flat zone and graylevel reduction. This filtering consists of the 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, it is enough to classify the distributions in the histogram for simplification of those objects. The article also shows some experimental results, where the proposed method is compared to other classical methods applied to flat zone and graylevel reduction
