Foreground detection without an image sequence

I need to detect the foreground object on an image and cut it off from that image. There are lots of background/foreground subtraction or object recognition algorithms but these algorithms are working on the videos or image sequences. I have only an image (it can be a picture of a man in front of a white wall. ) as an input. Do you know any useful approaches that can be applicable on a single image file instead of video or image sequences.

search as an "saliency detection" like "Global contrast based salient region detection" http://mmcheng.net/salobj/

What you are looking for is a figure-ground segmentation algorithm. Does it have to be fully automatic? If you can draw an initial contour of the object by hand, you can use a class of algorithms called "active contours". If you need this to be fully automatic, you can use an algorithm called N-cuts.

If you are using MATLAB, and you are ok with semi-automatic segmentation, try the Image Segmenter App in the Image Processing Toolbox.
