Recent research in measuring web content credibility automatically for text and multimedia have addressed many languages. Unfortunately, there is no research for credibility measurements of Arabic web content. Thus, this paper proposes a solution to automatically measure the credibility of Arabic web content. The automatic tool we present in this paper measures Arabic content credibility published...
Recently, a lot of applications depend on data modeled by graphs. Efficient query processing over graph databases serves these applications. Having a graph query q, super-graph query processing finds all the graphs g in a database of graphs D where g is contained in q (gsubeq). Because graph databases contain a lot of graphs and because sub-graph isomorphic tests are NP-complete, an indexing-based...
This paper describes a new robust appearance-based method for representing and recognizing human behaviours using the eigenspace technique. This method has three main advantages over the existing appearance-based methods. First, the centering of the human-body blob, in each background-subtracted video frame, together with the use of an incremental procedure for compression, have made the extraction...
The bit error and packet loss in unreliable channels such as Internet and wireless networks lead the quality of video data unacceptable, which force us to take the network adaptive transmission into account. In this paper, we firstly propose a novel Greedy Spread (GS) ROI extraction method to extract ROI effectively, and then the network state changing is quickly perceived without occupying additional...
In this paper, a similarity evaluating model based on rough formal concept analysis and information content similarity is proposed which evaluates the similarity degree between the concepts. We use the information content approach to automatically obtain part of similarity scores of two concepts which makes up the normal featural and structural evaluating models. Then through our model, the similarity...
This paper presents an optimization methodology of hybrid multi-objective genetic algorithm for the real world optimization problem of facial analysis of multiple camera images by 2.5D Active Appearance Model (AAM). Facial large lateral movements make acquisition and analysis of facial images by single camera inefficient. Moreover non-convex multidimensional facial search space formed by AAM requires...
