Do you mean you want to calculate the location of a single white pixel? Or you want to determine if a given coordinate is a white pixel? Maybe a picture will help.

Let's say input binary image is image_bw
result=bwareafilt(image_bw,1,'Largest');
count_w=sum(result);
fprintf('The white pixel count is: %d',count_w);
