Speaker verification is the task of determining whether two utterances represent the same person. After representing the utterances in the i-vector space, the crucial problem is only how to compute the similarity of two i-vectors. Metric learning has provided a viable solution to this problem. Until now, many metric learning algorithms have been proposed, but they are usually limited to learnin...

Accurate estimating is one of the most important activities in the field of software project management. Different aspects of software projects must be estimated among which time and effort are of significant importance to efficient project planning. Due to complexity of software projects and lack of information at the early stages of project, reliable effort estimation is a challenging issue. ...

Abstl·act. In this paper, a metric for object oriented language is formulated and validated. On the contrruy of the other metrics used for object oriented programming (OOPs), the proposed metric calculates the complexity of a dass at method level and hence considers the intemal architecture of the classes, subclasses and member functions. The proposed met1ic is evaluated against Weyuker's propo...

—The paper contributes to video quality assessment of delivered content without reference. We propose a no-reference video quality assessment metric taking into account the behavior of the human visual system. The proposed metric called Weighted Macro-Block Error Rate (WMBER) is based on macro-block error detection and is weighted by visual saliency maps. Both measures are extracted from a part...

To avoid motion artefacts when merging multiple exposures into a high dynamic range image, a number of HDR deghosting algorithms have been proposed. However, these algorithms do not work equally well on all types of scenes, and some may even introduce additional artefacts. As the number of proposed deghosting methods is increasing rapidly, there is an immediate need to evaluate them and compare...

Making a distributed system adaptable to the dynamic variations in the user requirements is a big challenge in software industries. It is identified that the solution for the adaptability of such dynamic variations can be achieved through reflective middleware. In this paper an efficient solution is proposed by combining aspect oriented approach with reflective middleware. The significant featu...
