In the arts and sciences, as well as in our daily lives, symmetry has made a profound and
lasting impact. Likewise, a computational treatment of symmetry and group theory (the …

The inherent challenge of detecting symmetries stems from arbitrary orientations of
symmetry patterns; a reflection symmetry mirrors itself against an axis with a specific …

Humans take advantage of real world symmetries for various tasks, yet capturing their
superb symmetry perception mechanism with a computational model remains elusive …

We present a novel and effective algorithm for affinely skewed rotation symmetry group
detection from real-world images. We define a complete skewed rotation symmetry detection …

In this work, we present a new approach to interest point detection. Different types of
features in images are detected by using a common computational concept. The proposed …

We present a spectral approach for detecting and analyzing rotational and reflectional
symmetries in n-dimensions. Our main contribution is the derivation of a symmetry detection …

Symmetry is a crucial dimension which aids the visual system, human as well as artificial, to
organize its environment and to recognize forms and objects. In humans, detection of …

Efficient detectors of rotationally symmetric shapes are proposed by introducing a novel
concept of semi-shape signatures to overcome the main problem of projection-based …

Systems and methods are provided to facilitate architectural modeling. In one aspect,
repetitive patterns are automatically detected and analyzed to generate modeled structural …

The purpose of this paper is to detect and characterize geometric rosettes which are among
many different star-like motifs used in the most common Islamic Geometric Patterns. Based …
