| Abstract | ||
| Speckle noise is main problem in coherent images. This problem makes the processing of synthetic aperture radar (SAR) images is very difficult. Therefore, this paper proved the conjugation between the coherent nature for electromagnetic wave and the coherent speckle noise. In this research efforts detected to study the degradation noise for images, this is performed by adopting the multiplicative noise model. Non-adaptive filters are typically used for noise removal or to performing some type of image enhancement, in this work adopt traditional non-adaptive Mode filter, where these filter applied with window size (5×5) to remove speckle noise from SAR image. The result shows the best result to preserve the edges and produce high smoothing in homogeneous image regions. | ||
