How can I use morphological methods to count the number of cells ??

Hi ,

I have the following image ....

I want to Use morphological methods to count the number of different size cells.

Can any one help ??

Thx

do you want to count the circle objects in this image and label them

thx for reply , actually yeah I want to find the number of the circles

Don't know why it has to be morphological methods, but you could if you want (not how I'd do it). But you could do something like

numberOfRegions = sum(bwulterode(binaryImage));

[Christine Ak]

first thx for your replying , actually I have a homework in medical image processing course and it says: " Use Morphological Methods "

I know there are easier methods to count cells , but I have to find morphological one -_-

[Image Analyst]

bwulterode() is a morphological method. By the way, you were supposed to tag it as homework, so as to be honest. As it is, I just did your homework for you, which is against forum norms. I tagged it homework for you just now.

[Christine Ak]

actually I didn't know that before (( tagging as homework)) , Sorry Thxx By the way ^_^
