Are all text pixels 255 and no other image pixels 255? If so, just get a binary mask of the letters and erase

letterPixels = grayImage == 255;
grayImage(letterPixels) = 0;

Are the images color? If so then find the mask for all three color channels and AND them together. Might there be other pixels that are not text that could be confused as text? If so you'll have to determine what's different about those white pixels than the text white pixels, such as the size, shape, or whatever. If that happens, then upload an image where it's erasing incorrect things.
