MATLAB: Get (automatically) position of pixels that are white in the binary mask image

Question

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).

Answer 1

"Get (automatically) position of pixels that are white in my binary mask image"

Let suppose im1 is a binary image

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