How about:
imshow('pout.tif');
points = 200*rand(50,2);
hold on
plot(points(:,1),points(:,2),'r*');
% Now use min/max to determine bounding rectangle
min_x = min(points(:,1));
max_x = max(points(:,1));
min_y = min(points(:,2));
max_y = max(points(:,2));
% Use rectangle to draw bounding rectangle
rectangle('Position',[min_x min_y (max_x-min_x) (max_y-min_y)]);

In your image you should use [min_y, min_x, (max_y-min_y),(max_x-min_x)] to draw the rectangle.
