Abstracts: This project gives the detail of Remote Sensing multi-spectral image enhancement using Edge detection techniques and filters. A remote sensing image captured by satellite faces problems like point noise, blurred and inaccurate image. Point noise means unwanted signal in which pixels of an image are blurred due to the high frequency of signal. Our project includes experimental details of different remote sensing image enhancement techniques. Matlab 9 is used for carrying out the experiments. Our project includes different edge detection techniques algorithm and comparative effect of each method on multi-spectral remote sensing image. Other methods like filter and different image enhancement techniques are also used for the same purpose. The proposed method uses the combination of unsharp filter and canny edge detection technique for best result. Canny edge detection technique has best result than other edge detection techniques for various satellite images used during project. With the help of remote sensing images and applying edge detection techniques the roads, vegetation, buildings, vehicle edge information and other details has been discovered.
