比如下面的例子,车头前面部分明显有一个 gap,如果用上面的 flood fill,那么肯定前面也会被连通,但是使用 trapped ball,可以看到四周以及前面 gap 那里有一个圆形○的痕迹。 如果把 ball 的 size 设置的非常小 = 1 pixel 之类的,可能就跟 flood fill 一样了。 参考:...
This is a Flood-Fill Algorithm Visualizer. This algorithm is mainly used to determine the bounded area connected to a given node in a multi-dimensional array. visualizationpython3tkinterfloodfillflood-fillflood-fill-algorithmtkinter-gui UpdatedJun 3, 2020 ...
The first is the workflow of the proposed model, its mathematical model, and algorithm. This is discussed under the following heads. Performance evaluation of the proposed model FFMM is adopted is evaluated to understand how the proposed model works and this model is analysed using MATLAB and ...

The program’s algorithm works as follows: Creating a text file (CSV) with the following headers “Disaster type,”“Date,”“Location,” and “Impact.” Checking if the title/headline of the newspaper report or the body text includes (flood “OR” flash flood “OR” rain “OR” heavy ...
The second part of the rheological tests involved measuring the rheological properties of various mixtures of fly ash-clay-cement. Viscosity measurements were performed using an algorithm in which the shear rate was increased by 2.0 rpm every 30 s. The rheometer started at 2.0 rpm and data was ...

HEC-RAS on the other hand, is popularly used for a wide range of applications such as 1D, 2D, and combined 1D–2D modeling, solving the implicit solution algorithm allowing for larger computational time steps than with explicit methods, unstructured and structural computation mesh, and mapping ...
If the risk of flood disasters under climate and land-use changes can be predicted and evaluated, it will be conducive to flood control, disaster reduction, and global sustainable development. This study uses bias correction and spatial downscaling (BCSD), patch-generating land-use simulation (...
In this study, the maximum area threshold of the MFD algorithm adopted 66.7 ha to delimitate sub-watersheds. The sub-watersheds produced by the D8 algorithm with different area thresholds were mapped in Figure 4b–g. The hydrological tool of ArcGIS 10.3 is programmed basing the D8 algorithm....
