Pair-wise or two-way interaction testing requires that for a given numbers of input parameters to the system, each possible combination of values for any pair of parameters be covered by at least one test. Empirical results show that pair-wise testing is practical and efficient for various types of software systems [1]. The problem of generating a minimum test set for pair-wise testing is NP-co...

Camera stabilization is an important task for video analysis. In this report, we describe a method for estimating and stabilizing camera motion between two images via 2D image registration. Our approach is based on a pair-wise registration of images parameterized by 2D affine or projective transformation. Pair-wise image registration estimates transformation parameters for each pair of consecut...

– We use a Gaussian radial basis kernel function to map pairs of feature vectors from a sample into a fuzzy connectivity matrix whose entries are fuzzy truths that the vector pairs belong to the same classes. To reduce the matrix size when the data set is large, we obtain a smaller set of representative vectors to form a smaller matrix. To this end we first group the feature vectors into many s...

In this paper, the concept of k-regular fuzzy matrix as a general- ization of regular matrix is introduced and some basic properties of a k-regular fuzzy matrix are derived. This leads to the characterization of a matrix for which the regularity index and the index are identical. Further the relation between regular, k-regular and regularity of powers of fuzzy matrices are dis- cussed.

Intuitionistic fuzzy relations on finite universes can be represent by intuitionistic fuzzy matrices and the limiting behavior of the power matrices depends on the algebraic operation employed on the matrices. In this paper, the power of intuitionistic fuzzy matrices with maxarithmetic mean-minarithmetic mean operation have been studied. Here it is shown that the power of intuitionistic fuzzy m...

This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...

Comparing and classifying the three-dimensional (3D) structures of proteins is of crucial importance to molecular biology, from helping to determine the function of a protein to determining its evolutionary relationships. Traditionally, 3D structures are classified into groups of families that closely resemble the grouping according to their primary sequence. However, significant structural sim...

The goal of the present study is to propose use global connectivity measures as quantitative indicators long-term medication in pediatric patients with Attention-Deficit-Hyperactivity Disorder, combined type (ADHD-C). For this purpose, graph theoretical brain indices are computed from estimations across eyes-opened resting-state EEG recordings measured before and after treatment osmotic release...

A new hesitant fuzzy set (HFS)-ELECTRE for multi-criteria group decision-making (MCGDM) problems is developed in this paper. In real-world applications, the decision makers (DMs)’ opinions are often hesitant for decision problems; thus, considering the exact data is difficult. To address the issue, the DMs’ judgments can be expressed as linguistic variables that are converted into the HFSs, con...
