In this paper, a user independent human computer interface system using eye movement and blink feature detection is introduced. A hands free interface between computer and human can potentially replace the traditional human computer interface devices like mouse, keyboard etc. This technology is intended to give functionality to peoples with severe motor disabilities to control a computer by just moving their eyes. This paper describes a method of controlling the mouse cursor on a computer screen using the electrical potentials developed by eye movements known as Electrooculography. Electrooculography (EOG) signal is used to detect eye movement and blink features. The EOG signal is recorded from electrodes placed at appropriate positions around the eyes. The captured EOG signal is then analyzed to detect and classify eye movement features of interest. The detected features were then used to generate control signals to control a mouse cursor. The cursor control application is implemented offline. The detection accuracy for blinks, horizontal and vertical saccades are 100%, 97% and 93% respectively.

This paper presents a novel and robust method for pupil and iris boundary localization based on morphological and geometrical operation. This proposed method localizes the iris and pupil center in several stages. In the proposed algorithm Otsu threshold value, median filter, image complement, contact labeling and manual tracking are used for robust detection of the pupil. Otsu threshold is used for picking threshold value in order to determine the right binary image. Then edge point is used for the pupil boundary localization. The use of geometrical operation helps in better iris localization. Its performance does not degrade in case of seriously or partially affected eye images with eyelids and eyelashes. The proposed scheme has been tested on iris image databases like: CASIA-IrisV1 and CASIA-IrisV3. Experimental result demonstrates the supremacy of the proposed scheme in comparison with some other existing methods.

Internet access using mobile handheld devices has surpassed that of fixed Internet, but most web pages are designed for desktop browsers. Mobile devices have resource limitations. Consequently, web pages designed for desktop browsing cannot be well displayed on mobile devices. Thus, dynamically transforming web contents designed for desktops into contents which can be displayed in a mobile device is an important task. Various approaches of content adaptation have been proposed to achieve this goal, but no single content adaptation strategy has been found to be effective. On the other hand, e-learning contents have grown manifold over years. In this paper, we provide a framework for an e-learning content adaptation system that can be used with desktops and mobile devices seamlessly. We combine multiple content adaptation strategies to make e-learning contents appropriate for mobile devices. Among the various content adaptation strategies, the segmentation algorithm plays the most important role. Our experiments demonstrate that the proposed scheme can be successfully utilized for content adaptation in mobile and handheld devices.

Developing a Web mining scheme that takes plain text (for example, a paragraph of a story) as an input to generate multimodal learning materials from the Internet sources could be of great help to both teachers and children with special needs. This paper proposes a solution which at first extracts the keywords from the plain text provided using word co-occurrences method. The co-occurrence distribution between frequent terms and other terms in a sentence are used to define the relative importance of a term. Thus extracted keywords are used to search for the multimodal elements (texts, images and video clips) and other similar stories through search engine APIs (Application Programme Interface). After the search operation, URL (Uniform Resource Locator) filtering, domain filtering and Web content analysis based filtering methods are used to remove unwanted materials. The proposed scheme has been implemented, tested and verified by children through ethnographic method to demonstrate the merits and capabilities in generating multimodal learning. Results show that the proposed scheme offers on average of about 80% accuracy for learning material generation.

Mobile Ad-hoc NETwork (MANET) devices are generally powered by battery, and hence are energy constrained. In such a scenario, overloading nodes with forwarding data packets from other nodes leads to quick depletion of energy in the nodes and ultimately leading to its death, and hence network partitioning. Thus, in case of MANETs energy metrics like network lifetime, have to be given its due importance. However, the routing protocol must be flexible enough to allow network administrator to switch priorities between energy saving routing and least delay routing. Some papers have been written to cater to this need, like ESAR [19], EEAODR [20] etc. This paper proposes an improvement to the ESAR protocol, by replacing its energy metric with lifetime prediction. This improves the overall efficiency of ESAR protocol, while retaining the flexibility in regards to choosing between energy efficiency and least delay metric. Simulation results have shown improvement in performance in terms of energy efficiency in our proposed protocol.

Money transaction through ATM machine wherever we go has become phenomenon in our day-to-days activities as it is safe to keep a ATM card rather than keeping cash. When we need cash in any unknown area or during any emergency situation, we need to know about nearest ATM booth from where we can avail this opportunity. In addition, a tourist or new comer may face difficulty in having ATM help without this information. Hence, we have proposed a location based ATM locator system (LBALS) using OpenStreetMap, a growing open source digital map where ATM booths and fast tracks are mapped. Database contains detail information about all available ATM booths and fast tracks of different banks. It requires GPS supported android device with application installed on it for the user. Textual information are provided of nearest ATM booths or fast tracks from user's current position when he requires the information. Some Markers indicate ATM booths or fast tracks on the map. Dijkstra's algorithm has been applied to show the possible shortest path between user and an ATM booth. Haversine formula is also used to calculate perpendicular distance. Implemented LBALS is tested for some random locations in a specific region of our country.

Semantic analyzer determines the semantic meaning of the words in a sentence. This paper proposes a semantic analyzer that can semantically parse the Bangla sentences. Without semantic analysis, it is very difficult to find the accurate meaning of the translated sentences in one language into their equivalent sentences in other language. To analyze the Bangla sentences semantically, this study identifies a set of features of each word categories in Bangla. Experimental results show that proposed features can be used effectively for analyzing all kinds of Bangla sentences with semantic analyzer.

Web Geographic Information Systems (WebGIS) have been introduced for fulfilling the growing need of Geographic Information Systems (GIS) in the Internet. WebGIS can also be used to manipulate the published data according to the user's need. However, publishing of large volume interactive vector data might degrade the performance of WebGIS, due to upload/download and rendering time. In this paper, a vector data manipulating and publishing architecture named MapBeing is proposed which provides features to manipulate and publish huge volumes of data on maps without degrading performance. The proposed architecture consists of four core layers named User End, the Request Handler, Service and Data Provider. The User End layer is constructed using an open source JavaScript library called OpenLayers which shows vector data on the interactive map presented on the web. The Request Handler layer processes data provisioning based on user interaction. GeoServer is used in the Service layer for map creation and modification and PostGIS, a Database for storing spatial data, is used as the Data Provider layer. The experiment shows that along with the ability to manipulate and publish vector data, the architecture also achieves significant amount of lower usage in user bandwidth.

This paper presents a robust image watermarking scheme for embedding gray scale watermark into RGB color image. The presented method is based on discrete wavelet transform (DWT), singular value decomposition and chaotic system. DWT and SVD are separately applied on three color planes (R, G and B) of original color image and watermark image for embedding and extracting processes. DWT and SVD techniques are used in the proposed watermarking scheme to increase the information hiding capacity and perceptual similarity of watermarked image. At the same time, chaotic system is also used in the proposed watermarking method to ensure the security of the watermarking technique by scrambling the watermark image. In the embedding stage, the gray scale watermark information is separately embedded into three color planes of the original color image. On the other hand, in the extracting stage, the watermark information is separately extracted from three color components and the final watermark is obtained by calculating the average of extracted results from three color components. The results of the proposed method are compared with other existing image watermarking methods. From the results, it can be seen that the proposed method outperforms the other existing methods by giving high values of peak signal to noise ratio (PSNR) and low values of mean square error (MSE). The proposed approach also shows well robustness against different types of attacks than other existing methods by providing high values of normalized correlation (NC).
