Spatial Frequency and the Performance of Image-Based Visual Complexity Metrics

IEEE Access, 2020
There is a wide range of visual and spatial complexity measurement methods that aim to quantify perceived image complexity. While image-based calculation methods (edge detection, image compression, contrast) characterize a digital image, visual ...

Region-wide temporal and spatial variation in Caribbean reef architecture: is coral cover the whole story? [PDF]

, 2010
The architectural complexity of coral reefs is largely generated by reef-building corals, yet the effects of current regional-scale declines in coral cover on reef complexity are poorly understood.

EVOLUTION OF SPATIAL COMPLEXITY IN ROMANIA: NETWORKING, DIFFERENTIATION [PDF]

Revue Roumaine de Géographie, 2013
The spatial complexity is negatively correlated with regional specialization. Demonstration of how regional specialization has been evolving has relevance in studying the dynamics of spatial complexity.
