Magnetic Resonance Imaging is one of the most important medical imaging techniques for the investigating diseases of the human brain. A novel method for automatic segmentation Magnetic resonance brain image framework is proposed in this paper. This method consists of…

This paper imports the fuzzy logic into image retrieval to deal with the vagueness and ambiguity of human judgment of image similarity. Our retrieval system has the following properties: firstly adopting the fuzzy language variables to describe the similarity degree…

This paper focuses on color differences among the edges of objects in an image. The variations of colors among the objects in the image can depict the directions and simple geometric shapes of most objects in the image regardless of…

In some cases, low resolution of those images composing a video film hinders the proper visual interpretation of its data. A typical example of this is video obtained from security cameras. There thus exists the need to count with some…

This paper presents a neuro-fuzzy network where all its parameters can be tuned simultaneously using Genetic Algorithms. The approach combines the merits of fuzzy logic theory, neural networks and genetic algorithms. The proposed neuro-fuzzy network does not require a priori…

Who uses requirements engineering and design methodologies besides the people who invented them? Are researchers -at least- actually trying to use them in real-world complex projects and not in "paper project"? In this paper, we dare to recount the experience…

Modern requirement engineering approaches divide the elicitation process in two different stages: one focused on analyzing the context where the system-to-be will be used and another centered on designing software solutions appropriated to the context modeled. An adequate framework for…

Systems development methodologies continue to be a central area of research in software engineering. As the nature of applications and systems usage move increasingly towards open networked environments, not only are new methodologies required, but new ways for evaluating methodologies…

Early measurement of software size allows to estimate costs and effort as well as to plan the development schedule. In previous reports, an approach which applies the Function Points Analysis to the derivative Scenarios of the Language Extended Lexicon was…

This article presents a procedure for constructing a taxonomy of COTS products in the field of Requirements Engineering (RE). The taxonomy and the obtained information reach transcendental benefits to the selection of systems and tools that aid to RE-related actors…
