  • The purpose of this study was to analyze the use of the e-learning courseware which is about the properties of earth environmental change. I made these materials using Lectora program, and to have more visual effect, I used movies and animations as much as possible. A lot of movies and pictures are added to help student understand the geographical age. Especially the forms of performance test questions are various, and student can check the answer right after taking test. Because of this, they can get a immediate feedback. In addition, this allows you to adapt yourself to the age of information by using the internet. Every plug-in is already linked together, so you only need to once. Pictures and moving reflections can be edited with ease. I hope this study will provide valuable aid for the education of earth science and a chance to develop better materials.

  • In this paper, we propose a new accurate and robust image mosaic technique of the mural underdrawing taken from the infra-red camera, which is based on multiple image registration and adaptive blending technique. The image mosaicing methods which have been developed so far have the following deficits. It is hard to generate a high resolution image when there are regions that do not have features or intensity gradients, and there is a trade-off in overlapping region site in view of registration and blending. We consider these issues as follows. First, in order to mosaic Images with neither noticeable features nor intensity gradients, we use a Projected supplementary pattern and pseudo color image for features in the image Pieces which are registered. Second, we search the overlapping region size with minimum blending error between two adjacent images and then apply blending technique to minimum error overlapping region. Finally, we could find our proposed method is more effective and efficient for image mosaicing than conventional mosaic techniques and also is more adequate for the application of infra-red mural underdrawing mosaicing. Experimental results show the accuracy and robustness of the algorithm.
