Good day Anu,

here is an ImageJ-macro that does what you want for the provided sample
image:

//// macro start
run("Set Measurements...", "area redirect=None decimal=9");
setOption("BlackBackground", false);
run("Make Binary");
run("Dilate");
doWand(0, 1140);
run("Make Inverse");
run("Set...", "value=255");
run("Select None");
run("Invert LUT");
run("Analyze Particles...", "  show=Nothing display clear include add");
run("Measure");
exit();
//// macro end

Paste the above macro code to an empty macro window (Plugins >> New >>
Macro) and run it.

The results table lists 203 areas with size in pixels^2.

HTH
