I perform similar tasks. While there are probably some internal methods inside python, I make calls to ImageMagick to perform the image manipulation. I first write a baseline tiff with the tfw with gdal_translate then preform convert commands to do the image processing then gdal_translate again to turn the baseline tiff and tfw back into a geotiff.
