This question is almost impossible to answer without a) the image in question, and b) your definition of what the "background" is. Please upload your image (see the "Image" icon in the editor where you post your question) and provide some details as to your criteria for distinguishing foreground from background. Also, do you have the Image Processing Toolbox?

Looking at the image, how do you want to define the "foreground"? There are three polar bears in the image you supplied. Do you want to identify only the one closest to the camera? If so, this is potentially quite difficult, as standard thresholding techniques based on color matching would likely not work. I guess you would need some way to identify the "sharpness" or "in focus" portion of the image (edge detection?). Perhaps someone on this forum with more experience in this area can assist.
