Abstract

The speckle noise is inherently generated in the SAR image during the phase of image acquisition/ capture. It has bad impact on the SAR image. The SAR image holds lot of useful information due to its various major applications like climate monitoring, agricultural land and forestry monitoring, and many more. If the quality of the SAR image is good then much useful information can be retrieved from it but if the quality is not good then there is problem in extracting out necessary information. The quality factor is highly dependent on the presence of speckle noise in the SAR image. Therefore the pre-processing step i.e. SAR image despeckling is a mandatory step in the generation of the SAR image. This paper describes some of the conventional and non-conventional SAR image despeckling methods and compares them on the basis of two factors i.e. qualitative and quantitative measures.
