The network where the resources are shared, to minimize the network overload the data rate must be adjusted used by the sender. The packets are dropped due to some routers are not able to forward the packets, so due to the bottleneck condition leads to many packet drops. May be the dropped packets already travelled a long way in the network and thus consumed significant amount of resources. So congestion leads to decrease the network throughput. This type of situation occurred on the early Internet, the development of the TCP congestion control mechanism. The major cause of network congestion...

La segmentation d'images est l'une des techniques les plus couramment utilisées dans le traitement des images numériques. Dans la segmentation d'image, la détection des bords d'une image réduit considérablement la quantité de données et filtre les informations qui peuvent être considérées comme moins pertinentes, en préservant les propriétés structurelles importantes d'une image. Ces derniers temps, de nouveaux algorithmes de détection des contours sont publiés chaque année et parmi ceux-ci, l'algorithme de la ligne de partage des eaux, qui est basé sur la morphologie...

Mathematical morphology especially watershed algorithm based image segmentation has been found to occupy an important place in the second level of digital image processing. The output segmented images should be suitable and conducive to the computer machines for subsequent processing. Already a few standard algorithms have been invented and have been established without any apparent pitfall in them. In spite of the quality of their studies, there are a lot of scopes and subareas which are apparently non exhaustive and may still left for further studies. This book aims at to carry out research...
