Several ways. Since the sample seems to be centered, simply crop your image with imcrop.
Another way is to use the whole image but get rid of blobs touching the border with imclearborder() and get rid of small remaining specs with bwareaopen().
Another way is to do a background correction so you don't get that junk in the bottom in the first place. To do that you need to divide your image by an image of a uniform gray sheet.
