How to extract more objects after watershed segmentation
显示 更早的评论
hello, i am trying to extract these two parts of tooth on this picture (penis and egg shapes). problem is that the tooth parts are surounded by bone, which is very similar to the tooth structure (similar intensity, eccentricity, perimeter, solidity). I am not able to find some parameter that is different with bone and tooth. Problem is that we have houndrends of images like this, where bone size / tooth size changes
should i try some filtering?
I am not able to succeed with regionprops.
Thank you

There are several things you could try to extract those two regions only. It might be a multi-step process. I could do it easily for this image, though I'm not sure it would work for other images. For example you could use
binaryImage = labeledImage> 0;
binaryImage = bwareafilt(binaryImage, 2);
Or you could try asking for solidity and Euler number.
Attach your labeled image in a .mat file if you need more help.

is this what you meant with the labeledImage or it was something else? because this code over here doesnt work :(
segment = watershed(dist_map);
labeledImage8 = bwlabel(segment, 8);
binaryImage = labeledImage8> 0;
binaryImage = bwareafilt(binaryImage, 2)
%last functions takes the two bottom regions (black and white) as the 2 largest regions

Just attach your labeled image in a .mat file and I'll do it for you.
save('labeledImage8.mat', 'labeledImage8');

See attached.
Note that your labeled image does seem to connect to another region so you might try to improve your segmentation algorithm.
