I am using water-shed segmentation to segment objects (porous). But areas with NaN value set by codes, is still shown in segmented image (highlighted in color with other objects). Can anyone give me a clue? Thank you.

Thanks for reminding. Below is the code to convert to NaN value. for coloum = 1:width for row =1:height if (I(row,coloum)==0 | I(row,coloum)< 25) I(row,coloum)= nan; end end end In segmentation, I didn't mention any NaN value (only imopen, imclose, then segment).
