Parallel Image Component Labeling With Watershed Transformation
The parallel watershed transformation used in grayscale image segmentation is reconsidered in this paper on the basis of the component labeling problem. The main idea is to break the sequentiality of the watershed transformation and to correctly delimit the extent of all connected components locally, on each processor, simultaneously. The internal fragmentation of the catchment basins, due to d...
متن کاملParallel Marker Based Image Segmentation with Watershed Transformation Parallel Marker Based Watershed Transformation
The parallel watershed transformation used in grayscale image segmentation is here augmented to perform with the aid of a priori supplied image cues, called markers. The reason for introducing markers is to calibrate a resilient algorithm to oversegmenta-tion. In a hybrid fashion, pixels are rst clustered based on spatial proximity and graylevel homogeneity with the watershed transformation. Bo...
متن کاملParallel Marker-Based Image Segmentation with Watershed Transformation
The parallel watershed transformation used in gray-scale image segmentation is here augmented to perform with the aid of a priori supplied image cues called markers. The reason for introducing markers is to calibrate a resilient algorithm to oversegmentation. In a hybrid fashion, pixels are first clustered based on spatial proximity and gray-level homogeneity with the watershed transformation. ...
متن کاملPractical aspects Parallel watershed transformation algorithms for image segmentation
The watershed transformation is a mid-level operation used in morphological image segmentation. Techniques applied on large images, which must often complete fast, are usually computationally expensive and complex entailing ecient parallel algorithms. Two distributed approaches of the watershed transformation are introduced in this paper. The algorithms survey in a Single Program Multiple Data...
متن کاملA parallel marker based watershed transformation
The parallel watershed transformation used in grayscale image segmentation is here reconsidered on the basis of markers. The goal is to reduce the typical over segmentation by decreasing the number of catchment basins produced by flooding. Assimilating the set of basins with a weighted neighborhood graph and computing the minimum spanning forest in which every tree is rooted at a marked vertex,...
