Hello, i do have a logical image (since i applied a binary mask) and i would like to have the position (x,y) of all the pixels that are white (background is black), automatically, withouth needing to click it.

I have tried 'bwconncomp' but it gives me the indice pixels (in a cell array) instead of the position and since the image is logical type, it gives an error when i want to transform it into position since its a cell array (i.e ind2sub doesnt works with cell arrays).

Let suppose im1 is a binary image

[r c]=find(im1==1);

It works but i dont know how to insert it into the loop (if not the code will be too much big, since i will have to create 15 images)

-I cant create a 3D matrix of zeros and saving each x,y in one dimension like i did for INT because i dont know the exact dimensions that find will provides me.

I guess the easiest form will be concatening the results in a 3D-matrix like A=[x,y,k] but i dont know the form exactly.
