There are many algorithms that use seeded region-growing. This one in particular plays off the idea of cellular autonomy. Not sure if it’s the same as what you’re calling, “Seeded Region Growing Segmentation.”

I think you could easily modify the code to have more than two competing regions. Check the original paper – I believe the authors discuss this.

Overlapping cells would be a challenge for this algorithm. For that you may consider shape-constrained active contours.

can growcut algorithm be used for nuclei segmentation of medical images. can this algorithm segment multiple objects or cells in a single image. can this algorithm handle overlapping of nuclei or cells.

Is this the same algorithm as ‘Seeded Region Growing Segmentation’?

SIR,
Can you give me some suggestion how to segment overlapping cells using matlab

assert shouldn’t be needed to run the algorithm – you can just comment that out.

good morning sir

in the GROWCUT algorithm, assert function is not present in the zip file.

can you send me the assert function for testing the algorithm please.

sir,
is it possible to extract a particular cartoon character from pictures and save it without background information

@Jay
type following code to create label image.
Here nn=6 which means you can choose first 6 piexel as foreground piexel and next 6 piexel as background piexel. You can choose more piexel by changing nn value.

img=imread(‘brain.png’)
imshow(img);
nn=6;
[y,x]=ginput(nn);
hold on;
x=round(x);
y=round(y);
disp(‘Select background piexel’);
[yb,xb]=ginput(nn);
xb=round(xb);
yb=round(yb);
label1=zeros(m,n);
for i=1:nn
a1=x(i);
b1=y(i);a2=xb(i);
b2=yb(i);
label1(a2,b2)=-1;
label1(a1,b1)=1;
end
labels=double(label1);

Shawn,for gray scale image i selected maxC=360.62 as per your formula. Is it right?
