The two-dimensional picture array generating model E2DCFPG introduced here is more general than the ET0LAS in [11]. A study on controlling the application of the tables as done in [11] by a control language might further increase the generative power and thus might help describe more complex picture languages. The idea of interpreting letter symbols in a picture array by primitive patterns is a well-known technique to obtain interesting classes of “kolam” [10] pictures or chain code [5] pictures and so on. We can employ this technique to generate such picture patterns as an application of the extended 2D CF picture grammars. There are many application areas of two dimensional array grammars such as character recognition [1],region filling algorithms[4] and soon. It remains to explore the capability of the theoretical model proposed here for such application problems.
