29 Mar 2010 ploterr plots data with x and/or y error bars and supports logarithmic scaling for both axes. Author: Felix Zoergiebel

have you tried distance transformation before WST? there is a Matlab function BWout=bwdist(BWin).
i got this from my class notes by Prof. Alex Hartov

hi, Rob
sorry for rating my own code. it is really not my purpose. i thought you have to click 'submit' for the rating to come out. and i haven't found a way to delete it.
you are right about the data type. it is really something i should consider.
the property of the slide bar can be changed in the GUI. select the slide bar, right click and select property inspector, and change the min and max value to expend the range. you might get an error when the threshold value is negative or more than one. i am not sure if it will help.
i'll also comment out the top hat part. i have a newer version GUI but don't want to upload it since it is really a minor change.

have you considered resizing your image before processing? enlarge them so each cell will have more pixel?

hi, Rob
thank you for the comments. that is what i am looking for.

i just uploaded a new GUI. hope you'll find it more user friendly.
to answer your question about the filtering parameter, it (i.e., the slide bar) changes the threshold values in the conversion from gray to BW.
if the bodies are touching, maybe the following link is useful to you

thank you

06 May 2014 Neuron counting Count the number of fluorescent cells (tagged with GFP) on noisy background fluorescence Author: TIAN ZHOU David

I really like the idea here, but I found too many problems right from the beginning. Every button that I push besides "browse" in the GUI returns an error.

To me, it's just not worth the time to dig through the code and try to fix this.

could you help me for making the 1- Please count number of peperoni. Using a GUIDE GUI based matlab function
