In every one of the images in that .zip file, the background has already been removed.

Removal of background is what you do when you have a picture of a real object, or at least a model of that object whose picture has been taken. For example if you had a picture of an apple sitting on a plate, you would need to remove the plate (and the table and everything else that was not the object of interest.)

sir i am doing dust particle monitoring project for this i have to remove all background expect dust particle from the image... What should i do? Could you suggest me some matlab codes?

Sneha Rauniyar I recommend you start a new Question, and post a couple of images. You will need to clarify how you know whether a particular dust particle is a foreground dust particle to be kept, or a background dust particle to be removed.
