Feature Extraction for Java Character Recognition

Feature extraction is very important in the process of character recognition. A good feature of the character will increase the level of accuracy for the character recognition. In this research, the feature extraction experiment of Java characters is done, where those features could be used for Java character recognition later. Before performing the process of feature extraction, segmentation is performed to get each Java character in an image, and followed by skeletonization process. After skeletonization process, feature extraction is done including simple closed curve, straight lines and curve. Several experiments was done using various parameters and Java characters in order to obtain the optimal parameters. The experiment results of simple closed curve and straight line feature extraction are quite good, respectively reached 82.85% and 74.28%. However, the result of the curve detection is still not good, only reached 51.42%

Design and Implementation of Skeletonization

The development of image processing technology is well developed today, such as object recognition in an images. Algorithm to obtain accurate results in object recognition continues to be developed. One example is the handwriting recognition application. This application is usually used to archive records or documents from physical form such as a notebook or a letter in the form of files digital. One of the initial process in image processing is image segmentation, and one of the methods used is skeletonizaton.

Design of Adventure Indonesian Folklore Game

These days traditional thing has been left behind not only by adults but also by children. One of them is folklore. It disappears because its package cannot interest the people. It needs a better package that interests a lot of people, for example game. The game took folklore theme that would teach the children about morale values. This game was made based on PC game because electronic device are increasingly in demand and with adventure game-based which is a game genre that a lot of people like including the children. This game was made by Unity3D which is can place the objects that we use easier. Besides, camera setting which is a feature of Unity3D can make the setting of the 2D graphics easier. First of all, the folklores need to be parted into the playable-part and the non-playable-part. In playable-part, the player needs to solve some tasks to play the next folklore. In non-playable-part, the game will show an animation. This folklore game can interests the children to become a better person from the morale value. But, it is hard to implement folklore into adventure game for some folklores. For example Origin of Mahakam River’s Creek that has some complicated detail to express the setting of the story.

Adding a Transparent Object on Image

Nowadays, image manipulation, which is related to matting and compositing process, is commonly used. Processed object may vary, however matters may arise when the object is transparent. Not many research has been conducted about the issue due to the difficulties in extracting transparency value and object refraction. In this research an application to execute matting process of a transparent object and compositing it into a new image is developed.

Multimedia Design for Learning Media of Majapahit

Majapahit was one of the last major empires of the region and is considered to be one of the greatest and most powerful empires in the history of Indonesia and Southeast Asia. However, learning history is became unpopular to young generation. Interactive media can help society to learn history enjoyable. This interactive multimedia will allow the reader to interact with combination of text, image, sound, and animations of Majapahit. There are three aspects of disccusion which are economics, politics, also arts and cultures. Each aspects will provide information related with Majapahit. From the results of questionnaire can be conclude that interactive multimedia form is more interesting than history’s books which full of text. The audience is satisfy with the utility and interaction form. Their knowledge also improve after they use the application.
