Sentence examples for by the watershed algorithm from inspiring English sources

These markers are subsequently used to enforce regional minima within a topological surface used by the watershed algorithm.

The segmented objects include: 1) real buildings;   2) non-building objects with strong backscattering;   3) artificial objects caused by the watershed algorithm when a region partitioned by the external markers has no internal markers in it.

real buildings; non-building objects with strong backscattering; artificial objects caused by the watershed algorithm when a region partitioned by the external markers has no internal markers in it.

Thus, dividing local minima, detectable by the watershed algorithm, disappeared.

For example, with respect to the Rand index, the performance of the developed algorithm was 91% as compared to 78% achieved by the watershed algorithm (data not shown).

Areas corresponding to "dense" tissues were subdivided into smaller objects by using the watershed algorithm.

In general, tracking procedures consist of two steps: (i) relevant objects are segmented from the background in each frame by using, for example, the watershed algorithm (Grau et al., 2004; Malpica et al., 1997; Vincent and Soille, 1991), and (ii) each of the segmented objects is then linked to the nearest object in the subsequent frame (Hadjidemetriou et al., 2004; Meijering et al., 2006).

On the one hand we performed an image analysis to estimate the nuclear packing density by direct counting of the cell nuclei either by manual counting or using the "watershed" algorithm of ImageJ, which was able to discern even between individual nuclei that lay in very close proximity or even partially overlapped (Figure 1A E).

The paper entitled "Efficient processing of a rainfall simulation watershed on an FPGA-based architecture with fast access to neighborhood pixels" by L. S. Yeong et al. describes a hardware architecture to implement the watershed algorithm using rainfall simulation.

The watershed algorithm therefore segments the picture into catchment basins.

Generally, a gradient image is used as input to the watershed algorithm.
