MATLAB: How do i meassure total surface area with regionprops

Question

Hey, I am trying to measure total surface area and perimeter of the mitochondrial networks. I used the regionprops function, however I can only meassure the area of single objects. When I try to sum everything together it either gives an error message, or the whole thing just equals one.

 %%Label items for quantification of total area
[mitLabel, mitNum] = bwlabel(Ibin)
mitStats = regionprops(mitLabel, 'Basic')
mitArea = mitStats.Area

I dont know what to do from here. All functions like sum(MitArea, 2, 'default') either fails or equals one. I just want to add all induvidal areas of components into one combined surface area.

Answer 1

Try this

allBlobAreas = [mitStats.Area]; % Extract all areas from structure into double vector.
totalMitArea = sum(allBlobAreas)
