the concepts of similarity and dissimilarity have been the interest of many researchers. basically, in the studies the similarity between two objects or phenomena, has been discussed. in this thesis, we consider the case when the resemblance or similarity among three objects or phenomena of a set, 3-similarity in our terminology, is desired. later we will extend our definitions and propos...
Starting instead from a symmetric-antisymmetric reformulation we first show SSIM to be a contrast or visibility function in the classic sense. Furthermore, the previously enigmatic structural covariance is revealed to be the difference of variances. The second step, eliminating the intrinsic quadratic nature of SSIM, allows a near linear correlation with human observer scores, and without invok...
Is it possible to calculate a hash value for a document that captures its salient characteristics, such that a repository can be queried for like values and retrieve all “similar” documents? If so, similar documents could be easily identified by a simple SQL query without the need for a full text search engine. Such a value would allow systems to quickly identify duplicate or similar content be...
There are different approaches to the temporal study of time evolving systems. In this paper, this study is carried out by means of the comparison of time series. It is proposed as an improvement in the comparison of time series with the inclusion of qualitative knowledge. Taking into account the evolution of the values of the series, our approach uses a similarity index defined by qualitative ...
Graph similarity search under the graph edit distance constraint has received considerable attention in many applications, such as bioinformatics, data mining, pattern recognition and social networks. Existing methods for this problem have limited scalability because of huge amount memory they consume when handling very large databases with tens millions graphs. In article, we present a succinc...
A wide array of molecular markers has been used to investigate the genetic diversity among common bean species. However, the best combination of markers for studying such diversity among common bean cultivars has yet to be determined. Few reports have examined the genetic diversity of the carioca bean, commercially one of the most important common beans in Brazil. In this study, we examined the...
