A multiresolution analysis was performed to estimate the large-scale structure of cosmological $N$-body simulations. To explore relations between the multiresolution analysis and the galaxy distributions, a method that is familiar to image processing engineering was utilized. We proposed a new technique for quantifying the large-scale structures, and found that this is useful to discriminate diffe...
