How to fill interior as different color

11 views (last 30 days)
Hi Mathwork community,
Using below code, i can get boundary as blue color and gaps filled as yellow color but i want to fill the interior as green color.
Thanks in advance for all help.
s = load('Result_matrix.mat');
Aorg = s.Aorg;
gapmax = 10;
[m,n] = size(Aorg);
A = double(Aorg>0);
P=[1 2 3;
8 0 4;
7 6 5];
Apad = zeros(m+2,n+2);
maxattempt = 10;
for niter = 1:maxattempt
Apad(2:end-1,2:end-1) = A>0;
B = zeros(m,n,8);
for k=1:8
[i,j] = find(P==k);
B(:,:,k) = Apad(i-2+(2:end-1),j-2+(2:end-1));
end
As = A>0 & sum(diff(B(:,:,[1:8 1]),1,3)==1,3)<=1;
[y,x] = find(As);
if isempty(x)
break
end
p = length(x);
xy = [x,y];
xy1 = reshape(xy,1,[],2);
xy2 = reshape(xy,[],1,2);
d = sum(abs(xy1-xy2),3);
d(d==0) = NaN;
i = (1:size(d,1))';
[dmin,j] = min(d,[],2);
keep = dmin <= gapmax;
i = i(keep);
j = j(keep);
for k=1:length(i)
xyi = xy(i(k),:);
xyj = xy(j(k),:);
dxy = xyi-xyj;
if abs(dxy(1)) > abs(dxy(2))
xr = linspace(xyi(1),xyj(1),abs(dxy(1))+1);
yr = round(interp1([xyi(1),xyj(1)],[xyi(2),xyj(2)],xr));
else
yr = linspace(xyi(2),xyj(2),abs(dxy(2))+1);
xr = round(interp1([xyi(2),xyj(2)],[xyi(1),xyj(1)],yr));
end
A(sub2ind(size(A),yr(2:end-1),xr(2:end-1))) = 3;
end
end

Fill the hole with imfill
Next you can color your integer image by defining the appropriate colormap
% Generate test image contains values in 0:4
[~,~,I]=histcounts(peaks,5);
I = I-1;
imagesc(I)
colormap([1 0 0; % color of 0 value
0 1 0; % color of 1 value
0 0 1; % color of 2 value
0 0 0; % color of 3 value
1 1 1])% color of 4 value
set(gca,'Clim',[-0.5 max(I(:))+0.5]);
colorbar

I fail to see the relationship between saving and coloring. What is your motivation of you asking unrelated question to this thread?
"Please post the question you might have each step as a series of indepent questions."

Hi Dear Bruno Luong,
i am using your above code to fill the gaps on boundary surface of cone but could not succeed to fill the gaps.
i have tried to change the ie. P=[1 2 3; 8 0 4;7 6 5] but its giving me errors.
Please guide me.
The file of cone with gaps on the boundary is attached.
Thanks for all your kind cooperations and guidance.
Regards
