Complex Wavelet Structural Similarity: A New Image Similarity Index
IEEE Transactions on Image Processing, 2009We introduce a new measure of image similarity called the complex wavelet structural similarity (CW-SSIM) index and show its applicability as a general purpose image similarity index. The key idea behind CW-SSIM is that certain image distortions lead to consistent phase changes in the local wavelet coefficients, and that a consistent phase shift of the

Enhanced structural similarity : an improved structural similarity index
2022The Structural Similarity (SSIM) Index is a very widely used image/video quality model that continues to play an important role in the perceptual evaluation of compression algorithms, encoding recipes and numerous other image/video processing algorithms.

Similarity Convergence in Residuated Structures
Logic Journal of the IGPL, 2005Summary: We introduce and study a notion of logical convergence in residuated lattices (with operators). We consider a convergence in similarity degree, rather than a bare order convergence -- the lack of symmetry of residuated lattices brings our approach closer to the logical structure than to the set of truth values.

Structural similarity and adaptation
1996Most commonly, case-based reasoning is applied in domains where attribute value representations of cases are sufficient to represent the features relevant to support classification, diagnosis or design tasks. Distance functions like the Hamming-distance or their transformation into similarity functions are applied to retrieve past cases to be used to ...

Similarity of RNA secondary structures
Journal of Computational Chemistry, 2006AbstractIn this article, we propose a relatively similar measure to compare RNA secondary structures. We first transform an RNA secondary structure into a special sequence representation. Then, on the basis of symbolic sequence complexity, we obtain the relative distance of RNA secondary structures.

Protein structure similarities
Current Opinion in Structural Biology, 2001Comparison of protein structures can reveal distant evolutionary relationships that would not be detected by sequence information alone. This helps to infer functional properties. In recent years, many methods for pairwise protein structure alignment have been proposed and are now available on the World Wide Web.

Structural similarity and diversity of sulfotransferases
Chemico-Biological Interactions, 1994In the present study, four new forms of aryl sulfotransferase cDNAs have been isolated and their structures determined. A compilation of primary structures of 16 different sulfotransferases, including enzymes metabolizing endogenous chemicals and xenobiotics, showed a considerable extent of similarity among bacterial, plant and mammalian species, and ...

Surprising similarities in structure comparison
Current Opinion in Structural Biology, 1996Examination of a protein's structural 'neighbors' can reveal distant evolutionary relationships that are otherwise undetectable, and perhaps suggest unsuspected functional properties. In the past, such analyses have often required specialized software and computer skills, but new structural comparison methods, developed in the past two years ...

Visualization of structural similarity in proteins
Journal of Molecular Graphics, 1991Two new methods for the visualization of structural similarity in proteins with known three-dimensional structures are presented. They are based on the degree of equivalence of alpha-carbon pairs in two proteins. The quantitative measure for residue equivalence is the comparison score generated using the sequence and structure alignment method of ...
