We have compared the results of multicolor UBVR and H{alpha} photometry for 169 young star-formation complexes in five galaxies using a grid of evolutionary models for young star clusters. The ages and interstellar absorptions are estimated for 102 star-formation complexes with the standard uncertainties {sigma}_t_=0.30dex and {sigma}_AV_=0.45mag. The accuracies of these parameters were verified using numerical simulations.
