How to perform watershed on this image

[Rohitesh Gupta]

Hi All,

I want to show distinction between cellular layer and non-cellular space on this image. Probably create a contrast and then apply watershed. Could anyone help on this.

Thanks,
Rohitesh

Dear Rohitesh,

The below macro code is doing more or less what you want on the image you submitted. No idea if it will work on other images you have but give it a go

title = getTitle();
run("Duplicate...", " ");
run("8-bit");
run("Bandpass Filter...", "filter_large=40 filter_small=3 suppress=None tolerance=5 autoscale saturate");
run("Find Edges");
run("Find Edges");
run("Find Edges");
run("Auto Local Threshold", "method=Contrast radius=15 parameter_1=0 parameter_2=0 white");
run("Select All");
run("Enlarge...", "enlarge=-1");
run("Crop");
run("Analyze Particles...", "size=25000-Infinity add");
selectWindow(title);
roiManager("Show All without labels");

Best wishes

Kees
