%0 Journal Article %T Medical Image Segmentation by MarkerControlled Watershed and Mathematical Morphology %A Ahmad El Allaoui %A M'barek Nasri %J International Journal of Multimedia & Its Applications %D 2012 %I Academy & Industry Research Collaboration Center (AIRCC) %X Segmentation by watershed transform is a fast, robust and widely used in image processing and analysis, but it suffers from over-segmentation. We present in this paper some improvements to this algorithm based on the mathematical morphology in order to get over this difficulty. The performance of this method isvalidated on medical images. The results obtained show the good performance of this approach. %K Image processing %K medical image segmentation %K watershed %K Marker controlled watershed %K reconstruction %K dilatation %K Mathematical morphology. %U http://airccse.org/journal/jma/4312ijma01.pdf
