For parallel computation, extensions to handle two-dimensional patterns are often required. In this paper we present a new type of regular expressions for two-dimensional patterns based on contours and their composition. Targeted applications comes from the area of modelling, specification, analysis and verification of structured interactive programs via the associated scenario semantics. %G English %2 https://inria.hal.science/hal-01514660/document %2 https://inria.hal.science/hal-01514660/file/978-3-642-40213-5_12_Chapter.pdf %L hal-01514660 %U https://inria.hal.science/hal-01514660 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC2 %~ IFIP-WG2-2 %~ IFIP-FSEN %~ IFIP-LNCS-8161
