Hi there,
I have the coordenades of two points, which with the function line() I can draw a line. I want to convert the pixels of the original image which belong the line between the two points. The image is binary.
In a graphical way: am trying to convert the pixels which go through the yellow line, in an automated way.
I am conscious that I could use the manually code, as example:
1 = BW_image(45:50, 65:70)
but I am trying to make it in a automated way.
Thank you!

One way.
T=false(size(BW_image));
T(A(1), A(2))=1; %line end point 1
T(B(1), B(2))=1; %line end point 2
BW_image=BW_image|bwconvhull(T);
