摘要：For decades, several image enhancement techniques have been proposed. Although most techniques require profuse amount of advance and critical steps, the result for the perceive image are not as satisfied. In this study, we proposed a new method to enhance the satellite image which using intelligent aspect of filtering and describe multi-threshold technique with an additional step in order to obtain the perceived image. In this way, several simple filters can be combined to form a more efficient and more flexible context dependent filter. This paper proposes a new idea for edge enhancement using smoothing techniques. Various smoothing technologies are explored and implemented for comparing their performance with various threshold values. Comparison is done by qualitative and quantitative approaches. From the results, specific filtering is only applied to the region for which it is suitable. We also evaluate the image quality. The proposed method shows dramatically increase in pixel distribution throughout the range of RGB. The result of this research is also beneficial in terms of geographical views due to the process which determined the difference appeared on each area.
