我正致力于“联接部件”标签,我的矩阵是:
1 1 0 2 2 2 0 3
1 1 0 2 0 2 0 3
1 1 1 1 0 0 0 3
0 0 0 0 0 0 0 3
4 4 4 4 0 5 0 3
0 0 0 4 0 5 0 3
6 6 0 4 0 0 0 3
6 6 0 4 0 7 7 7
并且现在,我想对第二点进行扫描,因为这样一来,我就做了以下编码:
for i=1:1:r
for j=1:1:c
if (bw(i,j)>=1)
if (i-1>0 & i+1<=r)
% if ( bw(i,j)~= bw(i-1,j) | bw(i,j)~= bw(i+1,j))
if ( (bw(i,j)~= bw(i-1,j) & bw(i-1,j)>0))
bw(i,j)= min (bw(i-1,j),bw(i,j))
elseif ((bw(i,j)~= bw(i+1,j) & bw(i+1,j)>0))
bw(i,j) = min(bw(i+1,j),bw(i,j));
end
end
if (j-1>0 & j+1<=c)
if ( (bw(i,j)~= bw(i,j-1) & bw(i,j-1)>0))
bw(i,j) = min (bw(i,j-1),bw(i,j));
elseif((bw(i,j)~= bw(i,j+1) & bw(i,j+1)>0))
bw(i,j) = min (bw(i,j+1),bw(i,j)) ;
end
end
end
end
end
disp(bw);
但问题是,在实行这一法典时,即取得以下产出:
1 1 0 2 2 2 0 3
1 1 0 1 0 2 0 3
1 1 1 1 0 0 0 3
0 0 0 0 0 0 0 3
4 4 4 4 0 5 0 3
0 0 0 4 0 5 0 3
6 6 0 4 0 0 0 3
6 6 0 4 0 7 7 7
only one value changes (2nd row, 4 col) in my result, whereas, I want:
1 1 0 1 1 1 0 3
1 1 0 1 0 1 0 3
1 1 1 1 0 0 0 3
0 0 0 0 0 0 0 3
4 4 4 4 0 5 0 3
0 0 0 4 0 5 0 3
6 6 0 4 0 0 0 3
6 6 0 4 0 3 3 3
有些人可以帮助? 什么地方会犯错?
