Journal ArticleDOI
Fluctuating Asymmetry: Methods, Theory, and Applications
TL;DR: Old and new methods of measuring fluctuating asymmetry are reviewed, including measures of dispersion, landmark methods for shape asymmetry, and continuous symmetry measures, and attempts to explain conflicting results.
Book
Computational Symmetry in Computer Vision and Computer Graphics
TL;DR: Recognizing the fundamental relevance and group theory of symmetry has the potential to play an important role in computational sciences.
Journal ArticleDOI
Real-time pattern matching using projection kernels
Yacov Hel-Or,Hagit Hel-Or +1 more
TL;DR: A novel approach to pattern matching is presented in which time complexity is reduced by two orders of magnitude compared to traditional approaches because of an efficient projection scheme which bounds the distance between a pattern and an image window using very few operations on average.
Journal ArticleDOI
Shadow Removal Using Intensity Surfaces and Texture Anchor Points
E. Arbel,Hagit Hel-Or +1 more
TL;DR: It is argued that the assumptions introduced in most studies arise from the complexity of the problem of shadow removal from a single image and limit the class of shadow images which can be handled by these methods.
Journal ArticleDOI
Matching by Tone Mapping: Photometric Invariant Template Matching
TL;DR: It is shown that, when tone mapping is approximated by a piecewise constant/linear function, a fast computational scheme is possible requiring computational time similar to the fast implementation of normalized cross correlation (NCC).
