The increasing use of multimedia streams nowadays calls for the development of efficient and effective methodologies for manipulating databases storing these streams. Moreover, content-based access to multimedia databases requires effective indexing schemes to facilitate the retrieval of the intended data. This work proposes two techniques to be used in generating color and texture indexes for ...

In this paper, a novel framework is presented to recover the 3D shape information of a complex surface using its texture-less stereo images. First a linear and generalized Lambertian model is proposed to obtain the depth information by shape from shading (SfS) using an image from stereo pair. Then this depth data is corrected by integrating scale invariant features (SIFT) indexes. These SIFT in...

among three branches of government, judiciary has the most important role in protecting of citizens’ rights; therefore upgrade and improvement of this branch is vital to promote human rights. if changes consider international standards and local concerns at the same time, be efficient, if not will be failed. good governance is an international model has localization capability which its default...

Kappa-like agreement indexes are often used to assess the agreement among examiners on a categorical scale. They have the particularity of correcting the level of agreement for the effect of chance. In the present paper, we first define two agreement indexes belonging to this family in a hierarchical context. In particular, we consider the cases of a random and fixed set of examiners. Then, we ...

The benefit of using indexes for processing coqjunctive queries in a database system is well known. The use of indexes in distributed database systems is equally justified. In a distributed database environment a relation may be horizontally partitioned across the nodes of the system and indexes may be created for the fragment of the relation that resides at each node. However, as an alternativ...

Frequent occurrence of large-scale cascading trip-off of wind turbine raises the concern about the decision process of ordered control of reactive power compensation devices. The theory of fuzzy multi-attribute decision making is adopted to ascertain the action sequence of reactive power compensation devices. First, a set of evaluation indexes including control sensitivity, regulation margin, r...

This article uses rough set theory for stability evaluation system of strategic alliance at first. Uses data analysis method for reduction, eliminates redundant indexes. Selected 6 enterprises as a decision-making unit, then select 4 inputs and 2 outputs indexes data, using DEA model to calculate, analysis reasons for poor benefit of decision-making unit, find out improvement direction and quan...
