Abstract A qualitative morphological classification is performed on a sample of hundreds of two-dimensional patterns found by numerically solving a nonlinear generalized Schrödinger equation within a region of parameters where these patterns coexist with non-trivial homogeneous solutions. The patterns found range from those very simple to others more complex. Apart from the shape, each pattern is also characterized by its chaotic content. Likewise, the interaction of the different pattern types is observed
