Skeleton Based Contour Line Generalization
, 2006 Contour lines are a widely utilized representation of terrain models in both cartography and Geographical Information Systems (GIS). Since they are often presented at different scales there is a need for generalization techniques. In this paper an algorithm for the generalization of contour lines based on skeleton pruning is presented. The algorithm is

Frequency Contour-Strip Method for Characterization of Damage in Structures under Noisy Conditions
Applied Sciences, 2021 Eigen-frequency, compared with mode shape and damping, is a more practical and reliable dynamic feature to portray structural damage. The frequency contour-line method relying on this feature is a representative method to identify damage in beam-type ...

The mid-level vision toolbox for computing structural properties of real-world images
Frontiers in Computer Science, 2023 Mid-level vision is the intermediate visual processing stage for generating representations of shapes and partial geometries of objects. Our mechanistic understanding of these operations is limited, in part, by a lack of computational tools for analyzing
