Tree-based picture generation

Tree-based picture generation

The concept of tree-based picture generation is introduced. It is shown that there are equivalent tree-based deenitions of four picture-generating devices known from the literature, namely collage grammars, mutually recursive function systems, context-free chain-code grammars, and 0L-systems with turtle interpretation. Furthermore, generalisations of each of these systems are discussed.

Flow-Based Automatic Generation of Hybrid Picture Mazes

A method for automatically generating a picture maze from two different images is introduced throughout this paper. The process begins with the extraction of salient contours and edge tangent flow information from the primary image in order to build the overall maze. Thus, mazes with passages flowing in the main edge directions and walls that effectively represent an abstract version of the pri...

Forecast-based scenario-tree generation method

Sometimes, the best available information about an uncertain future is a single forecast. On the other hand, stochastic-programming models need future data in the form of scenario trees. While a single forecast does not provide enough information to construct a scenario tree, a forecast combined with historical data does—but none of the standard scenario-generation methods is suited to handle t...

An Algebra for Tree-Based Music Generation

We present an algebra whose operations act on musical pieces, and show how this algebra can be used to generate music in a tree-based fashion. Starting from input which is either generated by a regular tree grammar or provided by the user via a digital keyboard, a sequence of top-down tree transducers is applied to generate a tree over the operations provided by the music algebra. The evaluatio...
