It is not clear. Please explain it to someone else and have them write it down and paste their explanation back here. Otherwise all I can say is try this:
outputImage = inputImage;
Everything from the input image will be preserved, including ALL moments.

Ah, finally now we're getting somewhere. Moment preserving THRESHOLDING. That thresholding word is important. You really didn't explain the algorithm though. So I have no idea what g1 and g2 are, given some arbitrary gray scale image. And the FAQ applies here.
But let's assume you have them and you calculated a threshold value of T according to your formula. Then you could binarize (threshold) the image into two levels (foreground and background) simply by doing this:
binaryImage = grayImage < T; % Or you can use <=, >, or >= if you want.
This will not preserve ALL moments, but may preserve one or a few of the moments if T was chosen appropriately.

Yes, I know that. How about 42 and 213 - will those do? If not, then why not?
