In geography, invariant aspects of sketches are essential to study because they reflect the human perception of real-world places. A person's perception of a place can be ex-pressed in sketches. In this article, we quantitatively and qualitatively analyzed the characteristics of single objects and characteristics among objects in sketches and the real world to find reliable invariants that can be used to establish references/correspondences between sketch and world in a matching process. These characteristics include category, shape, name, and relative size of each object. Moreover, quantity and spatial relationships—such as topological, or-dering, and location relationships—among all objects are also analyzed to assess consistency between sketched and actual places. The approach presented in this study extracts the reliable invariants for query-by-sketch and prioritizes their relevance for a sketch-map matching process. [-]

A Multilevel Road Alignment Model for Spatial-Query-by-Sketch
Tang, Ming; Falomir, Zoe; Sheng, Yehua MDPI (2020-11-01)A sketch map represents an individual’s perception of a specific location. However, the information in sketch maps is often distorted and incomplete. Nevertheless, the main roads of a given location often exhibit considerable ... -
Skewed mirror symmetry in the 3D reconstruction of polyhedral models
Piquer, Ana; Company, Pedro; Martin, Ralph Center of Computer Graphics and Visualization Faculty of Applied Sciences University of West Bohemia (2003)We aim to reconstruct three-dimensional polyhedra from axonometric line drawings. Existence of mirror symmetry in polyhedra can assist the reconstruction process. We present a new approach for determining planes of mirror ...
