do this process in two steps first create positive sample from single image you want to than create vector file of that
you need to make batch file write
createsamples.exe -img 33.jpg -bg neg/bg.txt -info info/info.lst -pngoutput info -maxxangle 0.5 -maxyangle 0.5 -maxzangle 0.5 -num 1000
this will create 1000 positive samples, be sure first make folder of name info
than create vector file
createsamples.exe -info info/info.lst -num 1000 -w 20 -h 20 -vec positives.vec
bg.txt is negetive file list in directory neg info refer to positive folder
another tip while HAAR training numpos should be 900 means if you have 1000 than minus 100 than only training work well
