I am trying to find out the droplet size distribution from a spray nozzle. So I have taken high speed imaging data for the same. Now, I want to find out the droplet size distribtion for a particular tiff file. I tried to write my own code, but it is not giving appropriate results. So, If anyone can help me out solving this problem then i would be greatful to him. Thank you.

We might be able to help if the droplets are all separated in your image. I have worked on several spray problems in the past. If your image is not good then you might have to alter/improve your image capture conditions, or else measure something else that is relevant, like area fraction or whatever.
It's a generic, general purpose demo of how to threshold an image to find blobs, and then measure things about the blobs, and extract certain blobs based on their areas or diameters.
If you have any more questions, then attach your image(s) with the paperclip icon after you read this:

Thank you Image Analyst. I think My image is good enough to work on and the droplets are also seperated enough as you can see in the attached jpg file. I wanted to plot drop size distribution (i.e. Number of droplets vs its diameter.) I tried my own code but I think it is not giving the correct results, If you can help me out in the same then i will be greaful to you.
Thank you.
