I was doing some exploring as I wrote a series of articles on the use of AI and creating mazes and found a paper from July 2007 on Image-Guided Maze Construction. The authors were Jie Xu and Craig S Kaplan from the University of Waterloo. Basically they looked into creating maze art using algorithms and computer graphics. They did a wonderful 25 minute video explaining the concept which is worth watching. You can find the video and read the paper (it is 10 pages and includes some great illustrations) at this link. While I cannot use the illustrations from the paper I can use my own work and research to show you what it says. Figure 13 is of particular interest where they convert a photograph of a mill into a maze !
What does the paper say ?
The paper "Image-Guided Maze Construction" talks about a technique for automatically making pictorial mazes from images. The system allows the designer to manually partition an image into a set of regions and then assign style parameters to each region. They are also able to sketch a schematic layout for the maze's solution path. The final maze will contain intertwined passages in each region, connected together by breaking walls between regions. In regular language, it speaks about taking an image, then making it into a maze that looks good by using the shape of the object in the image to create the pathways.
The paper describes four different maze textures: directional mazes, spiral mazes, random mazes, and user-defined lines. Each texture is controlled by specialized parameters. The paper also describes an algorithm for building mazes that respect the layout of a given solution tree.
The system has been implemented as an interactive application. The paper presents several examples of mazes generated by the system, including mazes based on photographs of the Great Wall of China, a portrait, and a discus thrower. It also shows pictorial mazes (which I call maze art) from the Francesco Segala - The world's first maze artist. Here is an image of his work, also shown in the paper, but this comes from Through the labyrinth : designs and meanings over 5000 years (2000) by Hermann Kern.
