Abstract

User interface design is a subset of a field of study called interaction with computer. A user interface is a collection of techniques and mechanisms to interact with something. In a graphical interface, the interaction mechanism is a pointing device of some kind. Interacts with is a collection of elements referred to as objects. Event-Driven  Software  (EDS)  can  change   state  based  on  incoming   events  common  examples   are  GUI  and  web applications.  GUI Testing is to check the look and feel of the application. UI Testing is the user interface testing which is done in front of the user. There are various tools are available for automated GUI testing and web application testing. The web application is built using asp, jsp, php, servlet. Here our specific contribution is to develop a single testing tool for testing both GUI and Web Applications together. GUI is built through the java technology. Various GUI and web based testing tools are compared.

Abstract

In medical image processing, brain tumor extraction is one of the challenging tasks; since brain image are complicated and tumor can be analyzed only by expert physicians. The location of tumors in the brain is one of the factors that determine how a brain tumor effects an individual’s functioning and what symptoms the tumor causes.  We have proposed a methodology in this paper that integrates k-means clustering and watershed algorithm for tumor extraction from 2D MRI (magnetic resonance imaging) images. The use of the conservative watershed algorithm for medical image analysis is pervasive because of its advantages, such as always being able to construct an entire division of the image. On the other hand, its disadvantages include over segmentation and sensitivity to false edges. The k-means clustering algorithm is used to produce a primary segmentation of the image before we apply watershed segmentation algorithm to it; which is an unsupervised learning algorithm, while watershed segmentation algorithm makes use of automated thresholding on the gradient magnitude map. It can be observed that the method can successfully detect the brain tumor size and region.

Abstract

This paper presents a new image indexing and retrieval algorithm by combining the color (RGB histogram) and texture feature (local derivative patterns (LDPs). Texture feature, LDP extracts the high-order local information by encoding various distinctive spatial relationships contained in a given local region. Color features, histogram extracts the distribution of various colors in an image. The experimentation has been carried out for proving the worth of our algorithm. It is further mentioned that the database considered for experiment is Corel 1000 databased. The results after being investigated show a significant improvement in terms of their evaluation measures as compared to LDP, RGB histogram.

Abstract

This paper focuses on hosting and analyzing medical diagnostic data using cloud computing. Cloud computing is a general term for anything that involves delivering hosted services over the Internet. This is a project proposal for medical database system using cloud computing. The proposed database system can provide new delivery models to make healthcare more efficient and effective, and at a lower cost to technology budgets.

Abstract

In this paper, a study on  fuzzy membership functions   for image segmentation using ultrafuzziness is conducted. In this work, Tizhoosh membership function which is totally supervised, Huang & Wang membership function and S-function are   considered. This work is an improvement of an existing work of Tizhoosh. Each membership function has its own merits and demerits in the computation process.  Using fuzzy logic concepts, the problems involved in finding the minimum/maximum of a entropy criterion function are avoided. We attempt to make it clear that identifying the better membership function to assign the fuzzy membership grade to every pixel in the image, for optimum image segmentation using ultrafuzziness. For low contrast images contrast enhancement is assumed. Experimental results demonstrate a quantitative improvement with S-function over other two other functions.
