You can use bwconncomp.
cc = bwconncomp(yourBinaryImage,4);
number = cc.NumObjects;

Here's yet another way
[labeledImage, numberOfObject] = bwlabel(binaryImage);

If you are planning to do something with those objects, you could be interested in using regionprops. Besides the number of objects within the image, you can retrieve any other property of the objects, such as the area, centroid, orientation,....
BW = imread('text.png');
s = regionprops(BW, 'Area');
N_objects = numel(C);
For all the options, take a look at
doc regionprops

I don't know what you want. By the way, the code above is not correct. It should say
N_objects = length(s)
That number will be the same regardless which attributes you measure (area, perimeter, or whatever).
