Bubbles moving and growing in a boiling fluid

Hi I already asked something similar previously and more of the people answered that the questio was too much generic so i will describe the problem in a properly way. So i'm study the boiling process for different fluids. I have to evaluate the dimensions of the bubbles that form on the surface. I have to evaluate the variation of the diameter during the time (because i have to evaluate the growing rate). To evaluate the diameter i have to approximate the bubble to something circular but the visualizations sometimes are not good enough to do this. I have also to find the value of the diameter at the departure. Then after evaluating the diameter i have to find the position of the center that is changing in each frame. Last thing i have also to evaluate the departure frequency. I have got a range of 500-1000 frames to analyse and the departure frequency could be higher than 100 Hz. Could you please give me some suggestions on how develop the code?
thank you for your attention.

"How to develop the code"? You mean like reading the "Getting started" section of the help? Or do you want us to give advice on an image analysis algorithm without actually seeing your image? Like I said in my response to your duplicate post: you did post your image somewhere didn't you? So I'm sure you've done that by now but you forgot to tell us where it is. So all I can say is to follow these general rules for image analysis
