Detection System of Illegal Logging Image Using Matching Process With Discrete Cosine Transform

摘要

To support the government monitoring system, Logging Detection Tool is used as an udimplementation of remote sensing technology. It prevents the forest from any damage due to illegal udlogging activity. Illegal Logging is an actifity of deforestation without any authority and causes many udproblems in some sectors such as economic, ecology and enviromental inbalance as a result of disruption udof the forests. The research is aim to create a system to detect the illegal logging, using Discrete Cosine udTransform (DCT). The Image Processing Stage is using index selection. The value of index is taken from udRGB Image that has been proceed with DCT and applied as the data to determine the forest location udbased on its damage. In this system, to reveal the site or forest location, it is derived from its damage level udthrough the selection of total of avarage index value and characterized as low, moderate and severe level. udImage sample is taken from reserved forests in Gowa, South Sulawesi, Indonesia. It has 750 m x 560 m udsize and using a sample image pairs in year 2007 as the initial data and year 2009 for the final data. The udtest results give the accuracy of the illegal logging detection system with DCT and it reaches 83.33%.
