Use bwconncomp() function for getting all blobs labelled in your image.

labelledImage = bwconncomp(originalImage);

regionprops() method with option 'all' will return you all information related to those blobs in stats variable.

stats = regionprops(labelledImage, 'all');

Now, for getting no. of blobs in your image, you can use below given two lines:

centroids = cat(1, stats.Centroid);

[row col] = size(centroids);

Once getting no. of rows and columns, you can iterate over blobs using "row" variable in a for loop and can do whatever you want to do.

for i = 1 : row

areaMatr(i) = stats(i).Area; % gives area for each blob in your image

%you can put your own logic here

end

Hope it helps.

To get all blobs in an image, you can use the iblobs function of the Machine Vision toolbox by Peter Corke: http://petercorke.com/Machine_Vision_Toolbox.html

hi all

i tried your idea but if there is a better idea that you can support me.?

first i'd like to thank all researcher who trying to support me with code or link or idea. thanks for god i solve my problem depending on the idea of my supervisor professor nasor allah moghadam /Tarbiat Modares University .

second thanks for all
