FWIW, we do appreciate your fixing them!

I hope she'd taken the hint and fixed it, but I guess not, so I just fixed it now, which you can see if you "show older comments." Sometimes when they post on a web site instead of posting to MATLAB Central, the web link is not correct because it's the whole web page with advertisements and all kinds of stuff, instead of just an image. In cases like that you have to right click on the image and say "View image" to get the true link to the image. Of course it's best to not use third party sites and just upload your image to MATLAB Central instead of someone else's web site.

Just threshold:
binaryImage = saliencyImage > 100; % or whatever.
% Fill holes
binaryImage = imfill(binaryImage, 'holes');
imshow(binaryImage);

sir if i have the manual mask... how to compute the background pixel and foreground pixel?

The mask is the foreground and background. There is nothing to compute. To compare you then just do an exclusive OR on the two images - your "true" one that you masked and define as being the absolute truth, and the binary image that you got from thresholding. Personally I'd trust the thresholding one as being the more accurate of the two so maybe to validate all you want is to show good correlation.
