Those images (well the three I opened) were already black and white. What does your original image look like?

I think you wanted to implement something like background subtraction to do that. I dont think just doing dilation and erosion will get your answer. So let me start with background subtraction, Here you need a camera which is not moving.(steady camera, better use a tripod or keep it over a table). Now take a frame where the object is not present, we can call it as background image. Now take an image with object.Then Subtract background image and new image pixel wise. Keep some threshold and if the value goes above that threshold in a pixel that means object is available in that pixel. Actually this wont give great results ,you have to use gaussian mixture models for that. Read my paper to get a better idea.
It helps to remove shadow also!!
