Process models play an important role in various software engineering contexts. Among others, they are used to capture business-related requirements and provide the basis for the development of process-oriented applications in low-code/no-code settings. To support modelers in creating, checking, and maintaining process models, dedicated tools are available. While these tools are generally considered as indispensable to capture process models for their later use, the initial version of a process model is often sketched on a whiteboard or a piece of paper. This has been found to have great advantages, especially with respect to communication and collaboration. It, however, also creates the need to subsequently transform the model sketch into a digital counterpart that can be further processed by modeling and analysis tools. Therefore, to automate this task, various so-called sketch recognition approaches have …
