segmenttiles.py comes with a help page (python segmenttiles.py --help) which explains the parameters in short. Most important segmentation can be done either by using a window or by looking for whitespaces in the image. Giving the width/height ratio or more specifically the tilesize makes guessing more accurate by discarding solutions that don't fit the given sizes. Furthermore by selecting equaltiles the segmenter will try to find a segmenting solution that results in having exact same size tiles. This can even improve segmentation results.
