在 MATLAB Online 中打开

Call regionprops(binaryImage, 'Centroid')

binaryImage = bwareafilt(binaryImage, 1); % Take largest only.
props = regionprops(binaryImage, 'Centroid') % Find centroid.
xCentroid = props.Centroid(1);
yCentroid = props.Centroid(2);

See the Image Segmentation Tutorial in my file Exchange for a full demo:

hi, I actually the code worked very well but the only problem was i have many blobs and the code just took the largest one. I want to include all blobs to get the centroid all. How can I do that, beside Is there any way to draw a specific area in the image to be the only interest area?
