Hi
Is there a way to detect the droplets in the attached image and draw a boundary around them with an acceptable accuracy?
My final purpose is to find the diameter of each droplet so that I can calculate the distributions of droplet size.
I have tried to use watershed cutting and imfindcircle, but the effect is not ideal.
Thank you for your help.

You can try with other color models. I got this by simply thresholding in the hsv color space.

Hi
It is my ynderstanding that you want to find the diameter of the circles/droplets in the image. You can do it using regionprops .
Here is an example for understanding the estimation of radii and centroid of circular object in an image.
