Using the mean field theory in the slave-boson approach we analyzed the
electron correlation effects in the stripe phases. One finds that a finite
next-nearest neighbor hopping $t'$ plays an important role in the low doping
regime, where it controls the crossover from the filled diagonal to half-filled
vertical/horizontal stripes at doping $ x\simeq 1/16$.
