Watershed algorithm is more relevant for image segmentation due to its ability to locate weak edges of adjacent regions with high accuracy and greater speed of computing. In this paper, a new watershed algorithm, based on distance transform, is proposed, which is applied to the image of lungs....
The watershed algorithm is a technique used for image segmentation. The segmentation here signifies that the image is partitioned into connected regions. Each region contains pixels having more or less the same characteristics. A region may be characterized by a mean value of gray levels, variances...
分水岭分割算法(WaterShed Algorithm),是一种基于拓扑理论的数学形态学的分割方法,广泛应用于数学、图像学和电子信息学领域。 一、算法原理 分水岭分割算法的基本思想是把图像看作是测地学上的拓扑地貌,图像中每一点像素的灰度值表示该点的海拔高度,每一个局部极小值及其影响区域称为集水盆,而集水盆的边界则形成分...

Watershed Algorithm(分水岭算法),顾名思义,就是根据分水岭的构成来考虑图像的分割。现实中我们可以或者说可以想象有山有湖的景象,那么那一定是水绕山,山围水的情形。而区分高山(plateaus)与水的界线,以及湖与湖之间的间隔或都是连通的关系,就是我们可爱的分水岭(watershed)。为了得到一个相对集中的集水盆,那么让...
Image retrieval based on content becomes a great focus in recently years. An algorithm for Image retrieval based on marker-based watershed is presented in this article. Watershed algorithm, a method based on mathematical morphology, which idea utilized in segmentation, used to cause the over-segment...
A novel algorithm based on watershed for color image segmentation was presented. The original color image was initially smoothed using peer group filtering in order to preserve the location of the edges. A homogeneity image was defined, which integrated gradient with local second-order moment ...
