Suppose you did something like
I = imread('cameraman.tif');
mask = I <= 64;
imshow(mask)
This particular approach turns a bit too much white, but it illustrates that you can turn part of an image white selectively with the rest turning black.
The rest of the task is in identifying your object (or person) of interest without selecting other things.
