The Flood-Fill Algorithm fills a connected area from a given point, regardless of boundaries, whereas the Boundary Fill Algorithm fills an area enclosed by a specified boundary color.
请叙述边界填充(Boundary Fill)和泛滥填充(Flood Fill)的基本原理基于两者之间的区别。相关知识点: 试题来源: 解析 答:边界填充算法的基本原理是:从多边形区域的一个内点开始,由内向外用给定的颜色画点直到边界为止。如果边界是以一种颜色指定的,则边界填充算法可逐个像素地处理直到遇到边界颜色为止。 泛滥填充算法的...
Boundary Fill is another algorithm used for the purpose of coloring figures in computer graphics. It is so similar to Flood Fill that many are confused as to whether it is another variation of it. Here area gets colored with pixels of a chosen color as boundary this giving the technique its...
Flood fill,also calledseed fill,is analgorithmthat determines the areaconnectedto a given node in a multi-dimensionalarray.When applied on an image to fill a particular bounded area with color, it is also known asboundary fill.
The proposed methods are based on morphological operations, shape analysis, geometrical coefficients calculations as well as the directional operation of flood fill with automatic selection of the stop criterion. The article presents also an innovative method of closing the boundary of an unrecognized ...
high tide. A maximum annual series of stream flows was used to inform the extreme value analysis to determine return periods and associated uncertainty. Channel flow depths associated with maximum stream flow at the desired return periods were used in the inundation algorithm to fill the floodplain...
Also, a global flood hazard mapping framework requires to consider the presence of internal conditions such as lakes, lagoons and reservoirs, and the boundary condition given by the sea level. In all the simulations performed, the sea level is given by the local “zero” of the DEM, although...

The combination of the denoising algorithm and ASTER DEM produced an inundation area of 450.95 km2 and a CSI of 0.57, which was closest to the flood extent derived using the MODIS imagery. Figure 10 shows a comparison in the spatial distributions of the flooded areas of the flood plain. It...
