Rudolf Arnheim has been known, since the publication of his groundbreaking _Art and Visual Perception_ in 1974, as an authority on the psychological interpretation of the visual arts. Two anniversary volumes celebrate the landmark anniversaries of his works in 2009. In _The Power of the Center_, Arnheim uses a wealth of examples to consider the factors that determine the overall organization of visual form in works of painting, sculpture, and architecture. _The Dynamics of Architectural Form_ explores the unexpected perceptual consequences (...) of architecture with Arnheim's customary clarity and precision.

We present an investigation into the relation between design princi- ples in Japanese gardens, and their associated perceptual effects. This leads to the realization that a set of design principles described in a Japanese gardening text by Shingen (1466), shows many parallels to the visual effects of perceptual grouping, studied by the Gestalt school of psychology. Guidelines for composition of rock clusters closely relate to perception of visual figure. Garden design elements are arranged into patterns that simplify figure-ground segmentation, while (...) seemingly balancing the visual salience of subparts and the global arrangement. Visual ‘ground’ is analyzed via medial axis transformation (MAT), often associated with shape perception in humans. MAT analysis reveals implicit structure in the visual ground of a quintessential rock garden design. The MAT structure enables formal com- parison of structure of figure and ground. They share some aesthetic qualities, with interesting differences. Both contain naturalistic asymmetric, self-similar, branching structures. While the branching pattern of the ground converges towards the viewer, that of the figure converges in the opposite direction. (shrink)
