Hi Faisal

I have do the change that you suggest and it can pass the
check_page_segmentation() function
however when I try to do the RegionExtractor for text columns/
paragraphs/ lines extraction it still didn't work quite well.
it return the whole image as one columns when the image actually
contain two columns, is there any way to work-around it?
thanks for the help

Cheers,
Leo
