Color image segmentation. In Image Processing and its Applications, 1992., International Conference on, pages 303–306. IET, 1992. 分水岭有很多不同的版本,这里仅以OpenCV的参考论文为例,详细介绍分水岭算法并且用numpy实现。如果要看官方例子怎么使用watershed,可以参考如下链接 Image Segmentation with Distance...
The watershed algorithm provides a complementary approach to the segmentation of an object. It is essential for segmenting objects where they touch their boundaries. Watershed is a dividing ridge between drainage areas. In digital image processing, the banks are the watershed lines and the drainage ...
In subject area: Computer Science Watershed Segmentation is a region-based method in computer science that treats an image as a topographic landscape, separating it into catchment basins based on pixel values or gradients, and is commonly used in medical image segmentation tasks. ...
Segmentation of MRI of brain regions is a challenging task. This paper investigates a pre-processing centric approach to segment the tumor region using watershed algorithm in an MRI image. Image enhancement and noise reduction techniques are used in pre-processing to enhance the quality of image. ...

Background/purpose: Automatic lesion segmentation is an important part of computer-based image analysis of pigmented skin lesions. In this research, a watershed algorithm is developed and investigated for adequacy of skin lesion segmentation in dermoscopy images.Methods: Hair, black border and vignette...
摘要: A major drawback when using the watershed transformation as a segmentation tool comes from the over-segmentation of the image. Over-segmentation is produced by the great number of minima embedded in t关键词: image analysis mathematical morphology watershed hierarchical segmentation waterfall ...
You have read about several ways to segment an image using the watershed transform. Another technique, known as marker-controlled watershed segmentation, is described on theImage Processing Toolbox page. To learn more about how to use the watershed transform in your own work, check out F...
In this paper an image-based method founded on mathematical morphology is presented in order to facilitate the segmentation of cerebral structures on 3D magnetic resonance images (MRIs). The segmentation is described as an immersion simulation, applied to the modified gradient image, modeled by a ge...
In addition, the technique is demonstrated on 3D MR data of the mouse head from which the cerebellum is extracted. Volumes of the mouse cerebellum and the mouse brains in toto are calculated. 展开 关键词: Practical/ adaptive filters biomedical NMR image segmentation medical image processing volume...
