    Convert 2D Images to 3D Image
    (Uva Wellassa University of Sri Lanka, 2012) Menikdiwela, M. P.; Ekanayake, Thushara
    Image processing gives a major contribution to the modern technology such as robot navigation, medicine, video games, three dimensional televisions etc. And also there are some places we cannot ever reach those places, which are war areas, space, deep sea etc. But we can get satellite images. Those images can be processed by image processing techniques. Therefore, recently image processing is a widely developing part of the technology. The 3D view means third dimension of depth which can be perceived by the human vision in the form of binocular inequality. Human eyes are located at slightly different positions which can observe different views of the real world. The brain is then able to reconstruct the depth information from these different views. A 3D display takes advantage of this phenomenon, creating two slightly different images of every scene and then displaying them to the individual eyes. With an appropriate disparity and calibration of parameters, a correct 3D perception can be identified 2D to 3D conversion is also an important step in image processing. By the support of MatlabOD software, it is possible to develop algorithms for 2D to 3D image conversion. MatlabĀ® is one of the major software in image processing, because it has its own programming language. Whole algorithm is run by the concept of stereovision. With two images of the same scene captured from the slightly different views and get the 3D view is identified as stereovision. Binocular stereo vision uses only two images.

    Mobile Based Travel Guide System
    (Uva Wellassa University of Sri Lanka, 2012) Weerasekara, M,K.; Dissanayake, B.A.K.
    Mobile phones have become a simple and common commodity while these devices can facilitate travel guidance due to their effectiveness and straightforwardness (Baus,et al.,2005). Mobile phones based travel guiding is promising to become the best-targeted guiding medium that offers fresh ways to their end users. Compared to the global mobile travel guide system context (Hinze and Junmanee, 2006), there's less development of such solutions locally. Therefore 'Travel Advisor' can be considered as an effective local solution for travelers. 'Travel Advisor' is mobile based travel guide system which was fully built using Java 2 Platform, Micro Edition (J2ME) and java library (Knudsen and Sing, 2005) for sending and receiving short service messages(SMS
