Hi guys, new in image processing here
i was wondering if there is a way to be able to detect the coordinates of white , in a black and white image? as matrix or something?

It would be helpful to know the larger context because knowing a list of row and column locations for a binary image is usually not needed, but here is what you asked for:
[rows, columns] = find(yourLogicalImage); % For a binary image
[rows, columns] = find(yourGrayscaleImage == 255); % For a uint8 gray scale image
