The objective of this work is to propose a segmentation method for retrieval images of Arabo-Moresque decors. It is a hierarchical segmentation using two successive watershed algorithm. The first watershed based on the Meyer's algorithm allows of identifies the germs which serve for the second watershed segmentation to achieve the segmentation. The proposed method is evaluated by using an ...

In this paper, we investigate the links between the flooding paradigm and the topological watershed. Guided by the analysis of a classical flooding algorithm, we introduce several notions that help us to understand the watershed: minima extension, extension map, and pass values. We investigate the possibility for a flooding to produce a topological watershed, and conclude that this is not feasi...

The human cortical surface is a highly complex, folded structure. Cortical sulci, the spaces between the folds, define location on the cortex and provide a parcellation into functionally distinct areas. A topic that has recently received increased attention is the segmentation of these sulci from magnetic resonance (MR) images, with most work focussing on the extraction of the sulcal spaces bet...

In this paper, a novel algorithm is proposed for the watershed transformation. This new algorithm is based on chain code. The traditional concept of chain code is first expanded into point-out chain code and point-in chain code. Then two theorems, which depict how to make watershed transformation based on chain code, are proposed and proved. In the end, the description of this new algorithm is ...

In order to further improve motion video object division detection accuracy and algorithm operating time and meet the real-time requirements, a motion video tracking algorithm based on memory watershed disc gradient expansion template is proposed in this article. According to the experiments carried out for the four standard video images, DGETMW algorithm can not only accurately detect the moti...

Watershed transform has been widely used in medical image segmentation. One fundamental problem with it is over-segmentation. There are mainly two approaches to deal with this problem: hierarchical segmentation and segmentation with markers. The markers, either automatically extractedor interactively generated, aremostlyused in thehomotopymodification of morphological gradients prior to the wat...
