Enhancing Remote Sensing Image Contrast based on Combination of Fuzzy Logic and Local Approach

The image enhancement methods are divided into 3 categories. These include histogram methods, fuzzy logic methods and optimal methods. Histogram based contrast enhancing methods modify histogram of images. Optimal methods are based on optimizing parameters. The fuzzy logic based image enhancement methods make image which quality is clearer than the traditional methods. However, these methods still use the global approach, therefore, it is difficult to enhance all land covered in remote sensing images. This paper proposes a new algorithm of enhancing the remote sensing images. This algorithm is based on combination of local approach and fuzzy logic.
