Please format your code by putting two spaces at the start of each line.

It could be an easter egg: http://www.mathworks.com/matlabcentral/answers/2001#answer_3188

but I don't really know since the deprecated function mmreader has finally been removed by R2014a and so I can't run it. Why don't you use one of the function that they've been recommending to replace it, such as VideoReader?

It's because you are assigning a value to img but using the value of image, which has the side effect of displaying the boy.

Replace

th = graythresh(image);

with

th = graythresh(img);

and likewise wherever you use image, to make your code consistent.
