Dear all, I have a problem for my project. I have a bunch of matrixs M by N by Z.
I binerized all matrixs and find the boundaries for each M by N matrix and apply them on original image same as the attached images (Red lines).
I would like to extract the information from cells which assign to a specific line.
To do this, I draw a shrinked border in black color and I would like to extract the information of the cells that the black line overlab with them.
Here I mean the black line which shows in the third image.

If xBlack and yBlack are the vectors that you plotted for the black curve, you can get the values underneath the lines by doing this
for k = 1 : length(xBlack)
v(k) = data(yBlack(k), xBlack(k)); % Note that y comes first because it's "row".
end
v will be a vector of data values at the black curve locations.

No, it was a seperate question actually, I am sorry if that was an inappropriate way to ask here in this discussion.
