I would like to compute the thickness of a layer in an image (image_1.png). I would like to do this by computing the pixel value in the top layer subtracted by the pixel value in the corresponding bottom layer and averaged over the entire layer

. Can someone help me how i could proceed with this?

Thank you

The bright pixels together form a layer of the lumen (seen in image_4.jpg). I would like to compute its thickness(from green line to yellow line). Segmentation edges at pixel i, with the superscript top and bottom indicate the top and bottom edges, respectively and n is the total pixel number.

I would really appreciate your help in computing the thickness for image_2.png or image_3.png.
